Comprehensive recycling production technology and comprehensive recycling system for defatted camellia cakes

Abstract

The invention provides a comprehensive recycling production technology for defatted camellia cakes. The comprehensive recycling production technology includes the steps of firstly, subjecting defatted camellia cake materials to two-stage crushing so as to obtain fine particles of the defatted camellia cakes; secondly, drying the fine particles of the defatted camellia cakes obtained in the first step, and leaching so as to obtain crude oil and wet meal; thirdly, subjecting the crude oil obtained in the second step to refining and purification so as to obtain a camellia oil finished product; finally, subjecting the wet meal to exsolution so as to obtain a camellia seed cake finished product. The comprehensive recycling production technology has the advantages that starting on the whole, the technology involves analysis of every process and optimization and integration sequentially, raw material granularity uniformity is selected as a basis for improving a subsequent technology, and the technical prejudice that cooking is required in an existing technology is overcome; through adoption of two-stage crushing, raw material granularity uniformity is improved, the whole technological process is improved, leaching effects are improved effectively, a necessary cooking step is omitted, and accordingly automation degree and energy utilization rate of the whole technology are increased.

Description

technical field [0001] The invention belongs to the technical field of camellia seed application, and relates to a production process and system for the comprehensive utilization of dry camellia cake, in particular to a production process and system for the comprehensive utilization of dry camellia cake. Background technique [0002] Camellia seed, also known as camellia seed, scientific name: Camellia seed, is the fruit of the camellia tree. Camellia oleifera is the main woody oil tree in my country, known as "Oriental tree", which belongs to the small evergreen tree of the family Theaceae Camellia, and is a unique woody vegetable oil resource in my country. Camellia oleifera is a unique oil tree species in my country. Camellia oil, also known as camellia oil, is a high-quality edible oil unique to my country, and its grade is comparable to that of olive oil. Camellia oleifera is full of treasures. Camellia oleifera is made from low-temperature pressing or low-temperature ...

AI Technical Summary

Problems solved by technology

Usually, the residual oil content in the dried camellia after the first oil pressing of camellia seeds still reaches about 5%. These dried camellia cakes (pieces) used to be discarded in the fields or burned as firewood, resulting in a serious waste of resources , will also have a certain impact on the environment

[0005] Therefore, to further process the dried tea and maximize the comprehensive utilization of the cycle, although there is a process for obtaining tea dregs through further processing in the prior art, there are still defects such as cumbersome procedures, high labor costs, and low automation.
