How to ensure the stability of flour quality and improve economic benefits?

The stability of product quality is the common pursuit of flour producers, operators and consumers. How to ensure the relative stability of the product quality is the problem that the flour milling workers have been pursuing and exploring. Summing up the experience of successful enterprises and famous brands, combined with years of in-depth practical research results, from the flour production process to explore ways to stabilize product quality.

1. Grain Quality Is Stable

1.1 A stable source of Wheat

The flour market competition, to a certain extent, is the capital and talent competition, embodied in the advanced, stability and innovation of material control and production technology.- maximize the funds to solve the problem of storage and.

Take different ways to establish a stable purchasing network.

Cooperate with local government or growers to establish order farming or cooperative cropping mechanism.

The establishment of regional professional associations or enterprises to form a community of interests, integration of resources, complementary advantages, mutual benefit.

1.2 Reasonable Blending

The raw material compounded reasonably is very important. Generally speaking, with mixed grain is divided into five steps:

Receiving mixed conditions of the factory to take more grain unloading at the barn, completed the first hybrid.

- run barn uniform bin automatic grading is inevitable. When the light wheat cleaning silo for wheat, more than 85% of the amount of storage capacity, should open a new position, and according to the proportion of adding variable.

The barn - net uniform storage, warehouse type according to the actual situation, the appropriate set in (a) bin homogenization device, unless a long time, about silo 10% should not be used independently. Flour produced from wheat at the bottom of the warehouse should not be used as a normal product.

1.3 Cleaning Effect Is Stable

"good clean finish milling half", in order to obtain a stable cleaning effect, we must do the following work:

Stable flow in the absence of wheat villosa flux scale plant, simply by wheat blending or inserted in the control flow is not reliable, simple and effective method is to add a flow control cabinet in the front of the equipment.

It is worth noting that the phenomenon of "heavy milling and light cleaning" is quite common, and some factories even have no special operation management. Export barn not export, wheat blending jam, feeding equipment or equipment in parallel nonuniform material, the screen surface or to stone surface clogging, sieve tube (plate), a hole or rupture bag wear, suction pipe blockage, water corrosion, water balance, air flow control failure, bin bottom product feed mildew and other phenomena occur, the key is not found in the first time, the cleaning effect caused instability. Must remember: cleaning equipment and process is not omnipotent, operation and maintenance can not be ignored.

1.4 And Stable Effect

We should pay attention to the following aspects:

Ensure the stability of wheat flow and the uniformity of original moisture.

The water quality is good, the water pressure is stable, the flow control is accurate and reliable.

According to the grain quality, water content, environmental temperature and humidity, tempering requirements, timely and accurate control of the tempering time and frequency.

STABLE 2. MILLING PROCESS

2.1 The Grinding Effect Is Stable

The following points should be done well:

Ensure the quality, flow and uniformity of incoming materials. Special grinding system supplies, must achieve the true meaning of "homogeneous merger"".

The mill running parameters are reasonable and accurate, and the work is safe and reliable.

The surface parameters of the grinding roller are suitable, the machining is accurate and the assembly is excellent.

Fine operation, strictly control the flour mill according to the requirements and indicators, rather than by personal experience and habits.

2.2 The Screening Effect Is Stable

The key point of stabilizing sieve effect is:

Establish an accurate and perfect maintenance system and strictly implement it.

Establish timely sieve path and screen adjustment rules.

2.3 Powder Cleaning Effect Is Stable

We should focus on the following points:

According to the regulation, the incoming powder cleaning machine working principle, incoming quality must be balanced, the same size, suitable for traffic.

The work of the state powder cleaning machine working state including: sieve amplitude, throwing angle, tilt angle of screen; the screen surface quality, tension, cleaning, horizontal suction configuration and adjustment. It is not difficult to find out the difference of each cleaning machine by observing and testing the working state of each cleaning machine.

The key is to control, fine material, screen, suction wind, coordination between movement and coordination.

3. Stable Flour

In the process of milling, the quality and quantity of flour extracted by different systems are different, even in the same system, there are differences in flour with different particle size range. Make good use of the uniformity and difference of the quality and granularity of the flour, and reasonably constitute the products that meet the needs of the users.

The 3.1 flour flow stability

We should pay attention to the following points:

Try to avoid grinding and screening. Flour mill requires homogeneous combination of raw materials, high square sieve feed also requires homogeneous combination. Otherwise, good mixing can not achieve the goal of powder extraction.

The flour was extracted from different quality and particle size, and the flour was subdivided into two parts. This reduces the repeated milling, increases the yield, reduces the consumption, improves the milling effect, and creates the condition for the composition and collocation of the flour.

Accurately grasp the quantity, quality, particle size range and change rule of each powder flow.

3.2 Stable Flour

Green, nutrition, safety and convenience are the mainstream of flour production and consumption. The use of flour improver must be under the premise of ensuring the quality of raw powder, comply with the provisions of the state, reasonable and stable addition.

The "change" of flour production is absolute, and "stability" is relative. Only by grasping the law of change can we find a steady way. In order to eliminate human error, we must strengthen the education of employees, improve the overall quality of staff occupation technology, strengthen the brand and quality awareness, establish and improve the system of quantitative operation and management process, stable product quality to solve the problem fundamentally, it is feasible and is the only effective.

Why Cleaning is so important in wheat flour milling machine process?

Wheat cleaning

1.  The purpose of wheat cleaning, due to the current technical constraints, wheat growth, harvest, storage, transportation and other processes will have impurities mixed. In the growing season, the wheat which is germinated and moldy because of too much rain and the wheat which is attacked by insects and diseases is the impurity in wheat, and the mixing of these wheat will affect the quality and odor of wheat flour.Therefore, in the milling wheat must be cleaned before, all kinds of impurities in wheat completely clean, so as to ensure the quality of flour, to meet the needs of the food industry and people's lives, to ensure people's health, and achieve the purpose of safe production.   

2. Classification of impurities impurities in the wheat can be classified according to the chemical composition and physical properties.

3.Common methods of wheat cleaning

(1)wind selection method  

The method of cleaning the air dynamics properties of wheat and impurities is called wind selection method.The aerodynamic properties are generally expressed as suspended velocities.wind selection method needs participation of air media.Commonly used air - selection equipment including vertical air duct and suction separator.

(2)Screening method 

The method of cleaning with different size of wheat and impurity is called screening method.Grain size is generally based on the thickness and width of wheat and impurities.The screening method needs to be equipped with a suitable screen for the movement of the sieve, and the relative motion of the sieve and the wheat is used to stratify the wheat.Small size and heavy flour would be pass through the sieve. The commonly used screening equipment has vibrating screen, rotary flat sieve and pre-cleaning screen.

(3) Using different grivatity of wheat and impurity to separate them.It is called gravity separation method. The gravity separation method needs the participation of the medium, and the medium can be air and water. The use of air as a medium is called dry gravity separation; the use of water as a medium is called wet gravity separation. The proportion of dry separation equipment commonly used gravity destoner, gravity separation, gravity separation equipment commonly used in wet stone wheat washing machine etc..   

(4) selection method using impurities and wheat geometry and different length of cleaning method called selection method. It is necessary to use the inclined plane and the spiral surface to separate the wheat and the spherical impurity by the different geometric shapes. The common buckwheat seed throwing vehicles and other equipment. The use of different lengths for cleaning requires a rotating surface with a pocket. The short grain embedded bag holes are taken away, and the long grains remain outside the bag holes and are not taken away, so as to achieve the purpose of separation. Commonly used equipment has drum selection machine, disc selection machine, disc roller selection machine, etc..   

(5) impact method by the impurity and wheat of different intensity cleaning method called impact method. Germination, moldy, diseases and insect pests of wheat, wheat and soil surface adhesion of dust, the adhesion strength is lower than that of wheat, the impact of the high-speed rotating component, broken off, the use of suitable mesh separating it, so as to achieve the purpose of cleaning. The impact of equipment commonly used are beating machine, impact machine, wheat brush machine etc..   

(6) magnetic separation method using wheat and impurity ferromagnetic different cleaning method called magnetic separation method. Wheat is a non-magnetic material, in the magnetic field is not magnetized, thus cannot be absorbed by the magnets; and some metal impurities (such as iron nails, nuts, etc.) is a magnetic material in a magnetic field will be magnetized by the magnet adsorption, which is separated from wheat. Permanent magnetic drum, magnetic steel and permanent magnetic box are commonly used in magnetic separation.

(7) Grinding method;

To clean up wheat surface dust or grind wheat straw by the use of rotating rough surfaces (such as sand grain) is known as the grinding method. It is widely used for peeling and milling. Through the grinding of the surface of a few sand rolls can partially separate the wheat flour, which can shorten the powder path and make it easier to pulverize. The commonly used equipment is like peeling machine etc.

In addition to the above methods, there are other methods,such as the one according to the color of the photoelectric sorting method, the equipment is color selection machine. The current application is not yet widespread as the equipment is very expensive. 

The cleaning system in wheat flour milling machine. Very important for get cleaning raw material wheat and then get the super and good quality flour.
