hot press oil extraction machine

According to the oil production temperature, it can be divided into cold pressing and hot pressing. Cold pressing sesame oil refers to the low-temperature pressing of sesame raw materials without high-temperature roasting. The sesame oil obtained by cold pressing has a light aroma, lighter color than hot pressing sesame oil, and higher colloid impurity content, acid value, and peroxide value than hot pressing sesame oil. It is suitable for cooking oil and high-quality salad oil. Hot pressed sesame oil bakes the raw materials and extracts sesame oil with the help of a hydraulic oil press. The sesame oil can be used as a flavoring oil with strong aroma and high oil yield. The residual oil rate in Youbing (Deep-fried round and flat dough-cake) can be reduced to an appropriate range and the production efficiency is fast.

The hydraulic press machine for oil extraction working principle is to use external mechanical forces to squeeze oil out of the oil material. The main physical changes that occur during the process are material deformation, oil separation, frictional heating, and water evaporation. During pressing, the internal and external surfaces of the pressed material particles are squeezed tightly under the pressure, resulting in two different processes of the liquid part and gel part, namely, the oil is squeezed out of the squeezed material gap and the squeezed material particles are deformed to form a hard Youbing (Deep-fried round and flat dough-cake).

1.As feed: Sesame residue contains rich nutrients such as crude protein and fiber, making it very suitable for processing and making feed for poultry, livestock, fish, etc.
2.Fertilizer production: Sesame residue is an efficient organic fertilizer that contains rich nitrogen, phosphorus, potassium, and trace elements. After fermentation, it can be used as fertilizer and has a good promoting effect on plant growth.
3.Food processing: Sesame residue can be made into sesame residue biscuits, sesame residue tofu, and other foods. Sesame seed biscuits are rich in protein and have a crispy taste; Sesame residue tofu contains rich dietary fiber.
