Full-automatic oil pressing system and oil pressing method

Abstract

The invention relates to a full-automatic oil pressing system. The full-automatic oil pressing system comprises a casing sequentially provided with a hearth and a combustion chamber from top to bottom, a material stir-frying device located in the hearth and in rotary connection with the casing, a first power device providing power for the material stir-frying device, a combustion smoke purifying device, a first exhaust fan, an outward discharge flue, a raw material container for containing raw materials, a first lifter for delivering raw materials in the raw material container to the material stir-frying device, a cooked material container for receiving and containing a cooked material discharged out of the material stir-frying device, an oil press for conducting oil pressing processing on the cooked material and a second lifter for lifting and delivering the cooked material in the cooked material container to the oil press, wherein the combustion smoke purifying device, the first exhaust fan and the outward discharge flue are sequentially communicated with the hearth. The process of oil pressing processing of the full-automatic oil pressing system is clean, hygienic, dust-free and environmentally friendly. The invention further provides an oil pressing method adopting the full-automatic oil pressing system. Automatic material frying and oil pressing processing is achieved.

Description

technical field [0001] The invention relates to the field of oil extraction processing, in particular to a fully automatic oil extraction system and an oil extraction method. Background technique [0002] Oil pressing equipment is used for the pressing production of various vegetable oils. Small oil pressing machine is a kind of oil pressing machine, which is mainly used for individual or family processing and pressing. Almost all oil crops can be pressed by small oil pressing machine , such as peanuts, soybeans, sunflower, rapeseed, walnuts, cottonseed, sesame, etc. The current small oil presses only have the function of pressing, mainly using pressure to squeeze the oil at room temperature. In order to increase the oil yield and the aroma and taste of the pressed vegetable oil, it is necessary to use additional frying equipment for the oil. The crops are fried. Then the fried and ripened oil crops are put into the oil press for pressing. The heating method of existing f...

AI Technical Summary

Problems solved by technology

The heating method of existing frying equipment generally adopts the mode of burning gaseous fuel or solid fuel, and the combustion of gaseous fuel and solid fuel all can have the shortcomings of insufficient combustion and smoke pollution, especially the use of solid fuels (such as coal, wood, etc.) etc.) During the combustion process, a blower must be used to blow air into the combustion furnace to increase the contact between fuel and air, so that the combustion can achieve sufficient heat, but this will cause the dust generated by the combustion to be discharged from the gap of the combustion furnace. Pollution to the processing environment and easy to pollution of materials

[0003] Due to the high temperature of the existing frying equipment, in order not to affect the work with the oil press and to avoid polluting the oil press environment, the oil press must be installed separately, and the fried and processed oil crops must be sent to the oil press very troublesome

Some large-scale oil extraction enterprises use conveying devices to realize the transportation of oil crops between various equipments, but the equipment occupies a large area and is not suitable for small processing enterprises. At present, there is no combination of frying, heating and pressing in the market. Integrated automatic oil extraction system
