Press equipment production line generally includes: vibrating screen, new drum frying pan (or electric heat transfer oil flat bottom wok, drum electric wok), new oil press, loading machine, centrifugal oil filter or vacuum filter oil press and other equipment .
Production line advantages:
The new press equipment production line developed by Zhaofang Machinery can be used for a variety of oil crops such as mustard seed, cottonseed, soybean, sesame, flax and camellia seed. The new press equipment production line can adjust the suitable temperature for different raw materials, easy to operate, and simplify the complexity of the fried material. In addition to the feed, basically no other operations are required. The production line can automatically control temperature, vacuum filtration, and easy operation. The area is small, the oil yield is higher than that of the same industry, the oil quality is pure, and it has the characteristics of energy saving and power saving.
Press production process:
1, hot squeeze: raw materials - cleaning - fried seeds - pressing - filtration - finished products
Operation instructions: According to the characteristics of raw materials, select the appropriate sieve for screening and then steaming, steaming and frying to make the oil temperature reach 110-120 degrees, and its water content is about l-1.5%, you can enter the oil press press. However, when adding seeds, add 2-3% water, and when frying to 110-120 degrees, you can press the pot.
2, cold pressing: raw materials - cleaning - pressing - filtration - finished products
Operation instructions: When cold pressing, the raw materials are cleaned and mixed, so there is no need to use the wok for the fried materials. The moisture content of the raw materials in the cold pressing directly affects the efficiency of the oil, so it is very important to judge the wet and dry of the oil. The general moisture content of the raw materials before pressing has a control standard.
For the problem that rapeseed oil is easy to appear in the pressing process: the oil content in rapeseed is as high as 33-40%. Generally, there is no abnormality in the operation of the book according to the instructions in the hot press. If it is cold pressed, it may be caused by improper operation or oil. The water is not suitable, and the temperature of the rapeseed oil press body is not good, and there may be phenomena such as running slag, returning oil or feeding.
