grape press

Abstract

A grape pressing machine is composed of a pressure-bearing frame, an air tank, a piston pressure plate mechanism, a material pressure-bearing basket and an air intake and exhaust device. The pressure-bearing frame is of a frame body structure composed of a pressure-bearing platform, supporting columns and a supporting cross beam. The pressure-bearing platform is located at the bottom of the frame body. The air tank is of a vertical cylindrical tank body structure and fixedly installed on the supporting cross beam. The piston pressure plate mechanism is composed of a piston plate, a piston push rod and a material pressing plate. The piston pressure plate mechanism and the air tank constitute a piston pressure device. The piston plate is installed in the air tank in a matched manner, so that an inner cavity of the air tank is divided into an upper tank cavity and a lower tank cavity which do not communicate with each other. The grape pressing machine has the beneficial effects that operation is easy and convenient, the pressing process is gentle, grape seeds cannot be crushed, and the squeezed grape juice is free from the influence of the smell of tannin; the juice squeezing process is shielded by an inert gas, so that the squeezed juice is not influenced by air oxidization; the air tank is stable in integrated structure, high in anti-pressure capacity and not prone to damage; and the pressing capacity of a pressing mechanism and the pressing process can meet various grape pressing demands.

Description

technical field [0001] The invention belongs to the technical field of wine brewing equipment, and in particular relates to a squeezing equipment for squeezing grape juice. Background technique [0002] At present, there are three types of grape presses used in wine production plants (châteaux) in major wine producing areas in my country: (1) airbag presses; (2) platen presses; (3) screw presses. Although these presses are mature in technology, their performance is single, and all have obvious deficiencies. The airbag press has excellent performance, but it can only be used for pressing general red grapes and grape pomace, not for ice grapes. Regardless of whether the airbag machine is an imported machine or a domestic machine, the cost of using the airbag is extremely high because the airbag is easily damaged, especially the imported machine is extremely expensive. The press plate press is easy to use, because the power transmission method is hydraulic or screw pressure, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome various deficiencies of the existing grape presses, such as: the pressure of the airbag press is small, and the airbag is easily damaged; The press is not suitable for pressing white wine and ice wine, etc., providing a press with the advantages of high pressure and soft pressing process, which completely makes up for the shortcomings of the above existing wine presses

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions to solve the above-mentioned problems: 1. Adopt an inflatable air tank pressure application method, pneumatic progressive pressure application, soft pressure application process, strong pressure bearing capacity of the air tank, and low consumption, effectively solving the existing problems There is a problem that the press cannot apply both soft pressure and high pressure intensity; 2. The grape pressure basket structure with a closed interlayer structure is adopted to create an inert gas environment, which effectively solves the problem of easy oxidation of grape juice in contact with air
