A feeding device for wine pervaporation membrane separation equipment

Abstract

This invention discloses a feeding device for a wine pervaporation membrane separation equipment, including a raw material storage device, a circulation device, a preheating device, a nitrogen addition device, and a product collection device. This invention utilizes a design with three insulated raw material tanks and a tank preheating system, ensuring that one raw material tank is always operational, one tank temporarily stores processed dealcoholized wine, and one empty tank awaits feeding. Thus, the transfer out of dealcoholized wine and the transfer in of new wine do not occupy system operating time. Simultaneously, the preheating system equipped in the tanks can preheat the raw wine to be processed. After the previous batch of raw wine is processed, the wine to be processed has already reached the required operating temperature, eliminating the need for additional preheating time and improving equipment operating efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of wine production, in particular to a feeding device of wine pervaporation membrane separation equipment. Background Art

[0002] Conventional pervaporation membrane separation equipment is designed for a single raw material tank. This equipment is used for membrane separation. After the raw wine circulation separation is completed, the dealcoholized wine is transferred out and then pumped into the next batch of raw wine. After heating, circulation membrane separation is performed. Because the raw wine tank is connected to the ambient air, the carbon dioxide in the wine escapes after the circulation starts, and at the same time, the aroma of the raw wine is taken out and lost. During the circulation process, as the liquid level in the raw material tank drops, air enters the raw material tank, and the oxygen in the air dissolves into the grape raw wine. Under the dual effects of oxygen dissolution and higher temperature, the product matures and oxidizes rapidly.

[0021] The use status of the present invention is:

[0022] (1) When the first batch of raw materials is produced, the raw wine enters the first raw material tank 3 through the feed pump 1, the plate heat exchanger 2, and the feed valve 20 on the first raw material tank 3. When the required liquid level is reached, the feed is stopped and the feed valve 20 on the first raw material tank 3 is closed;

[0024] (3) When the temperature of the raw wine reaches 40°C, the liquid ring vacuum pump 11 is turned on, and the alcohol and volatile aroma components in the raw wine pass through the preferential organic membrane in the membrane column group 9, change into a vapor state under low temperature and low vacuum, and are liquefied through the condenser 10 to form a liquid high-alcohol grape spirits, which enters the product tank 12;

At this time, the 40°C dealcoholized wine transferred from the first raw material tank 3 is heat exchanged with the 10-20°C raw wine fed into the third raw material tank 5 to reduce the temperature of the dealcoholized wine and increase the temperature of the raw wine to be processed. The preheating valve 16 on the third raw material tank 5 is opened to preheat the raw wine to be processed in the third raw material tank 5;
