technical field

The invention belongs to the technical field of squeezing; in particular, it relates to a vegetable oil squeezing device and a using method thereof.

Background technique

Vegetable oil is a compound composed of unsaturated fatty acids and glycerol. It is widely distributed in nature and is an oil obtained from plant fruits, seeds and germs. Such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc. The main components of vegetable oils are esters of straight-chain higher fatty acids and glycerol. In addition to palmitic acid, stearic acid and oleic acid, fatty acids also contain a variety of unsaturated acids. The fatty acids in vegetable oils can make the skin moist and shiny.

The production of vegetable oil is obtained by pressing, which is a unit operation in which the liquid phase is separated from the liquid-solid two-phase mixture by mechanical compressive force. The pressing technology is mainly used in the oil industry and the juice production of fruits and vegetables. Oil extraction is a method of extracting oil by extruding oil from the oil with the help of mechanical force. According to the depth of the extracted oil and the pressure of the material during pressing, the pressed oil can be divided into one pressing and pre-pressing combined with leaching and oil extraction. Compared with other oil extraction methods, oil extraction has the advantages of simple process, less supporting equipment, strong adaptability to oil varieties, flexible production, good oil quality, light color and pure flavor. However, the residual oil content of the cake after pressing is high, the power consumption is large, and the parts are easy to wear. This method can be used to extract oil from seeds or nuts such as cocoa beans, coconuts, peanuts, palm kernels, soybeans, rapeseeds, etc. In addition, another important use of pressing is to make juices, such as apple, citrus, tomato juice, etc.

For example, Patent Application No. (CN201811346104.2) discloses an automatic pressing equipment for edible oil production, comprising a bottom plate, a rolling box is installed on the bottom plate through a fixed mounting frame, the rear end of the rolling box is an open structure, and the rolling box A feeding frame is arranged on the upper side of the front end of the rolling box, an auxiliary groove is arranged on the upper end of the rolling box, the lower end of the rolling box is an open structure, and sliding grooves are symmetrically arranged on the inner walls of the left and right sides of the lower end of the rolling box. There are fixed holes symmetrically arranged on the left and right sides of the plant to complete the oil pressing operation, but the existing plants still have the following deficiencies in the pressing process:

1. The existing vegetable oil pressing device does not initially crush the plant during the pressing process of the plant, resulting in a low oil yield and a long pressing time of the plant during the pressing process;

2. The crushing process, heat treatment process and pressing process of the existing vegetable oil pressing are carried out separately, and each process is separated. Usually, the raw materials processed in the crushing process are manually transported to the heat treatment process, and then heat treated The raw materials processed in the process are manually transported to the pressing process, so that the raw materials processed in the crushing process cannot be transported to the heat treatment process in time for heat treatment, and at the same time, the raw materials processed in the heat treatment process cannot be transported to the pressing process in time. The pressing process causes the vegetable oil pressing speed to be too slow, resulting in low production capacity of the whole line, requiring a lot of manpower for transportation, and increasing the cost of vegetable oil pressing;

3. The existing plant has a pressing device for plant waste after pressing, and it is necessary to stop and manually discharge the residue, which not only increases the work intensity of the operator, but also reduces the pressing efficiency of vegetable oil.
