A kind of dust-free unloading and pretreatment method of cassava raw material

Abstract

The invention discloses a dust-free unloading and pretreatment method for cassava raw materials. Aiming at the problems objectively existing in the traditional technological process, the existing technological route and equipment performance principles are comprehensively and in-depth researched. The sand process should be modified according to the actual production conditions to effectively reduce the phenomenon of cassava dust flying, improve the on-site visibility, effectively ensure the safety of people, machines and objects in the area, reduce dust inhalation, and the pretreatment process can remove sand from cassava pulp The efficiency reaches 80%, which reduces equipment wear, improves fermentation quality, reduces labor intensity, and shows good social benefits.

Description

technical field [0001] The invention relates to the technical field of processing methods for raw materials in the ethanol industry, in particular to a method for dust-free unloading and pretreatment of cassava raw materials. Background technique [0002] With the rapid development of the world's fuel ethanol industry, the amount and price of crops such as wheat and corn are increasing day by day. The development of non-grain bio-ethanol has become the development trend of bio-ethanol technology worldwide. Compared with other crops, cassava has economic benefits and social benefits. The benefits are more prominent. For a long time, cassava alcohol technology has not clearly developed suitable production key technology and equipment according to the characteristics of cassava raw materials. However, the pollution and sand content of cassava raw materials have a great impact on whether various processes can be carried out better in the future. [0003] In actual production, b...

Problems solved by technology

Disadvantages of the original production process route: 1. The cassava at the station is manually unstacked, unloaded, and loaded in the open air. The entire operation area is seriously dusty and wastes cassava raw materials. At the same time, the unloading efficiency is low, resulting in personnel costs and resources. The cost of train delay remains high; 2. Trucks are used to transport bulk cassava within the company's area, causing environmental pollution around the transportation route; 3. Cassava raw materials are transported to the crushing workshop and then mixed with pulp for production, which is subject to the company's raw material ratio requirements and the design of the pulverizer itself, the existing pulverization capacity can no longer meet the subsequent mixing requirements, resulting in an increase in process energy consumption; and the cassava slurry has a large sand content, which is not suitable for non-wear-resistant centrifugal pumps in ethanol saccharification workshops and feed production. The horizontal screw machine wears a lot, resulting in frequent maintenance, discontinuous production, and a large amount of sediment accumulation in the fermentation tank, resulting in incomplete sterilization and seriously affecting the quality of fermentation
