Fruit and vegetable crushing, squeezing and coarse filtration technology and equipment application

In the production process of fruit and vegetable products such as juice and jam, fruit and vegetable crushing, squeezing and coarse filtration is a key process link, which can effectively extract the juice and intracellular substances in fruits and vegetables, retain the nutrients and taste of the raw materials, and provide basic raw materials for the preparation of the final product. This article will introduce the process flow of fruit and vegetable crushing, squeezing and coarse filtration, explore the equipment suitable for this process, and analyze its importance in the production of fruit and vegetable products. 1. Process flow Fruit and vegetable crushing, squeezing and coarse filtration refers to the process of washing, crushing, squeezing and coarse filtration of fruits and vegetables to finally obtain fruit and vegetable juice or fruit and vegetable pulp. Its main steps include the following stages: 1. Cleaning and sorting: First, wash the fruit and vegetable raw materials to remove surface impurities and pesticide residues, and sort and remove rotten or deteriorated parts. 2. Crushing and beating: The cleaned fruits and vegetables are crushed or pulped to break the fiber structure of fruits and vegetables, which is conducive to subsequent squeezing. 3. Squeezing: The crushed fruit and vegetable pulp is squeezed to extract the juice or liquid part of fruits and vegetables. 4. Coarse filtration: The squeezed juice or fruit and vegetable liquid is initially filtered through coarse filtration equipment to remove larger particles and solid particles to obtain relatively clear liquid. 2. Equipment application In the process of crushing, squeezing and coarse filtration of fruits and vegetables, a variety of equipment are involved, including crushers, presses and filters. The selection of these equipment will directly affect the efficiency and product quality of fruit and vegetable product production. 1. Crusher: Crusher is mainly used to crush or pulp fruit and vegetable raw materials. Common crushers include cutting crushers, stirring crushers, etc., which can effectively crush the fiber structure of fruits and vegetables and release juice and juice. 2. Press: Press can squeeze the crushed fruit and vegetable pulp to extract juice or fruit and vegetable liquid. Common presses include screw presses, hydraulic presses, etc., which have high extraction rate and stability. 3. Filter: Filters are often used in the coarse filtration process. Filters can remove large particles and solid particles in fruit and vegetable juice and provide relatively clear juice as product raw materials. 3. Importance Analysis Fruit and vegetable crushing, squeezing and coarse filtration are indispensable process links in the production of fruit and vegetable products, and have the following importance: 1. Increase production: Through effective crushing and squeezing, the juice components in fruits and vegetables can be fully extracted, the output of juice and jam can be increased, and the loss of raw materials can be reduced. 2. Maintain quality: The coarse filtration process can remove impurities and solid particles in fruit and vegetable juice, improve the purity and taste of the product, and maintain the high quality of fruit and vegetable products. 3. Improve efficiency: The use of professional equipment for fruit and vegetable crushing, squeezing and coarse filtration can improve production efficiency, reduce manual operations, reduce production costs, and improve the degree of automation of production lines. In summary, the fruit and vegetable crushing, squeezing and coarse filtration process and equipment have important application value in fruit and vegetable production, play a key role in improving product quality, ensuring production efficiency and reducing production costs, and are an indispensable link in the production process of fruit and vegetable products.
