2. Operating methods (part of the process, brief introduction of operation)

1. Selected raw materials:

The quality of starch has a great relationship with the selected raw materials. The yield of cassava powder in less than 10 months is low. Old cassava powder in more than 24 months has been qualitatively transformed, causing great difficulties in crushing and crushing, increasing the cost of reducing starch rate and affecting economic benefits. It is required that the first step is to put good raw materials into storage.

2. Cleaning and conveying:

The purpose of cleaning is to remove sand, soil, peel, reduce starch ash, and facilitate the next process. At the same time in the transport of cleaning, so uniform feeding, too many rotating cages without space, cassava can not roll, can not reach the purpose of peeling and cleaning. Too little is not enough to produce. Operators should also pay attention to the pressure of water, too low water pressure with no sediment, the general water pressure can not be less than 0.25 Mpa, always pay attention to the operation of the cage and conveyor, can not form a backlog of raw materials in this process. The machine usually works seven days with lube oil.

3. Fragmentation:

Because the cassava root is very long, it is lignified near the main stem, and can not be crushed unless it is crushed. The first purpose of crushing is to ensure the normal operation of the crusher. Some factories do not have crushing technology to increase the crusher load and reduce the service life. Second, in order to fully improve the yield and quality of starch and improve the yield of starch.

When operating, pay attention to observe the temperature of the motor and the sound of the machine, the sound suddenly becomes smaller, indicating that there is too much material in the crusher, at this time the amount of feed should be reduced. It is necessary to add proper amount of backhaul water, less material can not be taken away after crushing, more waste. In addition, to master the tightness of the triangle belt, the triangle belt is too loose, which reduces the efficiency of crusher. Too tight makes the motor load increase and damages the motor shaft. Therefore, the operator should concentrate, not leave the post, and strictly operate the rules. The quality of crushing directly affects the output of this class and the next process. The diameter of crushed block is generally 1 cm.

4. Crushing:

After crushing, the mixture of cassava pulp (about 1 cm in diameter) is put into the crusher. The comminution process is divided into one comminution and two comminution. Why two comminutions? One is because cassava is too long and there are too many lignified substances, such as one comminution, the yield of starch can not meet the requirements. The other is that one centralized comminution destroys the quality of cassava starch, which will crush large and small granules of cassava starch. It can make starch free sufficiently and increase the difficulty of filtering starch. So now we are divided into two crushing, the first crushed sludge, first into the first pressure curling screen, so that high-quality starch first filtered out, a pressure curling screen under the slag into a certain amount of backhaul water into the second crushing, after the second crushing of fine slag, then into the second pressure curling screen, such crushing. Advanced technology not only did not destroy the quality of starch, but also added backhaul water when crushing, so that the starch yield increased by 3-5%.

In the economic accounting of starch factory, water consumption and starch yield are two important indicators. Therefore, in the process of using return water and adding clean water, proper amount of return water must be mastered. There is a certain amount of return water from curved sieve, which should be fully connected with the previous process. The use of water can take away the crushed materials. It will not cause waste. The mill runs for an hour and then contacts the upper cover of the mill bearing with hand to see if the temperature rises, and then observes whether the temperature of the motor rises, and strictly controls the feed rate. Because there are too many lignified materials, it is difficult to crush. If the machine is not working properly, it should be shut down and cleaned. There is a square mouth above the crusher. First, the upper part is cleaned manually, then the pocket is connected to the mouth. When the machine starts cleaning, the lignified crushed materials are discharged thoroughly. When cleaning materials, special person should be responsible for starting switch to prevent accidents.

In the process of operation, attention should be paid to the amount of material stored in the ground pool of the crusher, and the transfer pump should be started in time so that the material can be sent to the upper working procedure. From cleaning and conveying to crushing, the whole equipment is continuous operation. After crushing, the slurry and slag are sent to the later process by the transfer pump. Therefore, the operators in this section will play an important role in the normal and continuous operation of the whole equipment.

Cassava chips, weighed with belt conveyor pulp, are fed into the cleaning cage at the speed of 100 kg/min to remove dust. The chips are fed into hammer mill twice by screw conveyor to crush. In order to reduce the flying of dry powder and loss, the chips are fed into pulp pool by induced draft fan through separator, and the pulp is fed into pulp pool by mixed flow pump. Pump into the impregnation tank and impregnate it with hot water at 40 C for 5 hours.
