A low-temperature screw oil press

Abstract

The invention discloses a low-temperature screw oil press, which comprises a press, and the press includes a press cage and a press head fixed at one end of the press cage, and the cake outlet head and the press head are arranged in a space formed by There is a screw press shaft, and the end of the screw press shaft close to the press head communicates with the outside world through the cake outlet of the cake outlet on the press head; the press cage communicates with the feeding funnel; the press cage communicates with the The feed funnel is connected, and also includes a frequency conversion motor and a frequency converter to control the speed of the frequency conversion motor. The frequency conversion motor drives the screw press shaft to rotate through a reducer; the diameter of the end of the screw press shaft close to the cake outlet It is smaller than the diameter of the end of the screw press shaft away from the cake outlet head. The invention has simple manufacturing process and small volume, improves the transmission efficiency of the oil press, improves the oil yield, and reduces the pressing temperature.

Description

technical field [0001] The invention relates to a low-temperature oil outlet device for continuously pressing vegetable oil, in particular to a low-temperature screw oil press. Background technique [0002] The output of my country's main oil crops ranks first in the world, but there are many mountainous areas in my country, such as soybeans, peanuts, rapeseeds, light bark trees and other oil plants are scattered, and the development direction of cold presses at home and abroad is mainly based on large-scale , Efficiency is the goal. It is inconvenient for these large machines to go to the countryside to work in the village. Therefore, a large part of domestic oil crops are not used to make oil or the utilization rate is very low, so that my country still needs to import about 2 million tons of edible oil every year. [0003] At present, the small oil press for household use usually needs to heat the oil, and perform steaming, frying and tempering treatment. After this proc...

AI Technical Summary

Problems solved by technology

[0003] At present, the small oil press for household use usually needs to heat the oil, and perform steaming, frying and tempering treatment. After this process, the protein in the oil will be denatured, the reusable value of the cake will be reduced, and the squeezed oil will It will also lose its original flavor and reduce its nutritional value

In addition, the speed control device of the small oil press for household use is mechanical friction transmission, which has low power transmission efficiency and high energy consumption.

[0004] "China Oils and Fats" (Volume 29, No. 6, 2004) discloses a small-sized cold press. The press shaft is segmented, and the screw pitch of the press cage is variable. The cold press is complicated in manufacturing process and bulky. It has no Using stepless variable speed motor, the speed is not adjustable, the pressing temperature is high, and the cake residual oil exceeds 10%.
