Pressing Method Of The Main Oil Crops

Pressing Method Of The Main Oil Crops:
1. Sesame: seeds before pressing fry into the light gray, situation has burst, knead by hand have seed oil outflow, when speculation seeds big speculation fire, temperature 120-150 degrees, thick cake O.7-1.5 mm, speculation suitable seed, the cake smooth flow of oil, the basic non-oil residue, as long cake shape, drain again.
2. Rapeseed: Since the North-South water mixed raw materials, pre-fried add 4-6%, the South do not add (based on the number of raw materials of the water itself), first with fire fierce fry until rapeseed hot, sound start has burst So far, then turn to open fire small seeds with reddish brown film was fried seed process, should not add water, when pressed rapeseed temperature to 120-130 degrees, about 1-1.5% moisture seeds speculation whether it is suitable from flow of oil to observe the status of the pie. Speculation suitable seed, the cake smooth flow of oil, the basic non-oil residue. Cake thickness l-1.5 mm, were small pieces, brown-red.
3. Groundnut kernels: fried peanut seed before the wet again, the process of speculation should also be appropriately seeds add water to make soft-jen good and sufficient moisture, then stir-fry until eight matured, knead by hand made kernels and skin separation, kernels can be broken into two-pressed into, the cake thickness O.7mm, cake-like wrinkles be arranged. Smooth out the oil.
4. Cottonseed Ren: oil before pressing fry into the flaxen, temperature 120 1 130 degrees, the cake thickness 1-1.5mm (the south, the north mixed with water, adequate water master).
5. Soybean:frying burst into edible before pressing, temperature 120-130 degrees, thick cake O.7mm. Drain again, but again expected to drain off the cake coke, to a large protein loss. Drain twice the general approach of the process. Soybean was fried six or seven mature pressing temperature to 80-100 ° C, moisture 5-6%, the first pass cake thickness 1.52mm, thick cake second time O.7mm, pie-shaped lines for the long bar, a oil is high, many deal with the volume.
