Tea oil residue hardened paste and oil pressing method

Abstract

The invention discloses a tea oil residue hardened paste and an oil pressing method, and can be used for oil residue hardening treatment and oil pressing treatment on oil residue hardened paste in the production process in various large, medium and small production and processing enterprises in tea oil production and processing industry. The technical characteristics are as follows: by utilizing the viscosity of tea oil residues and the adhesion effect principle of oil tea seed husk fragments, the tea oil residues and oil tea seed husk fragments are stirred and mixed to obtain uniform hardened paste, the paste is heated and subjected to extrusion forming, and the paste cake is subjected to oil pressing, so that the oil content of the tea oil residues is reduced from 50% to 5%. The invention overcomes the defects of low oil productivity and poor tea oil quality in the existing tea oil production and processing technique at home and abroad, can be widely used in various large, medium and small tea oil production enterprises, and enhances the oil productivity and tea oil quality.

Description

Technical field: [0001] The present invention relates to a kind of method that can be applied to the hardening treatment of oil dregs in the production process of various large, medium and small-scale production and processing enterprises in the camellia oil production and processing industry and the oil extraction treatment after the hardened oil dregs is pressed and extracted. Background technique: [0002] Camellia oil is a kind of oil that is widely used in delicious and nutritious dishes cooked in people's daily life for three meals a day. There are tea oil production and processing enterprises in various regions of our country that are carrying out the production and processing of tea oil to meet and enrich the market demand. At present, tea oil production and processing technologies at home and abroad include hot pressing oil extraction method and cold pressing oil extraction method. The amount of oil residue collected by precision filtration accounts for about 5% of...

AI Technical Summary

Problems solved by technology

The oil content in the oil residue is 50%. The oil residue is a paste-like flowable plastid. There are three disadvantages that cannot be repeated to extract oil and improve the oil yield. One is due to the viscosity of the oil residue itself. , when it is mixed into Camellia oleifera seeds and pressed repeatedly, it cannot be evenly stirred and mixed, resulting in the inhomogeneity and instability of the softness and hardness of the raw materials, and the gap between the pressing strips of the oil press cannot be automatically adjusted in place instantly, resulting in the oil content in the tea meal. There are more oil residues in the rise and crude oil; the second is that some camellia seeds stick to the pipeline wall due to the increase in viscosity, which affects the smoothness and uniformity of the camellia seeds to the oil press, resulting in uneven feeding. The disadvantages of empty pressing and jamming are formed; the third is that the entire camellia seed delivery system cannot be cleaned due to the incorporation of viscous oil residue, resulting in residual deterioration and reduced quality of camellia oil
