Food is fundamental to people's lives, and there is a significant emphasis on food safety. As a result, food production manufacturers pay great attention to the quality of water used in production. Many manufacturers use tap water directly as their production water, but this does not meet the water quality standards required for food production. Consequently, some manufacturers utilize reverse osmosis (RO) equipment. Let’s take a closer look at why these manufacturers choose to use reverse osmosis equipment in the food and beverage industry.
1. **Principle of Food and Beverage Reverse Osmosis Equipment:**
Reverse osmosis technology is a membrane separation technique driven by pressure differential. Similar to ion filters, it can remove a large number of impurities from water. The reverse osmosis process is the opposite of natural osmosis. To create reverse osmosis pressure, water pumps are required to apply pressure to the salt solution to overcome its natural osmotic pressure, allowing water to permeate through the reverse osmosis membrane while preventing impurities, such as dissolved salts, from passing to the other side of the membrane. Additionally, to prevent the concentration of dissolved salts from accumulating on the membrane surface, the concentrate water must continuously flush the membrane surface during operation, carrying away the concentrate and impurities on the membrane surface, thus completing the reverse osmosis desalination and purification process.
2. **Functions of Beverage Reverse Osmosis Equipment:**
By employing reverse osmosis technology for desalination treatment, the system's acid-base consumption is reduced by over 98%, achieving a desalination rate of 98%. The treated water is free of impurities and can be safely used in the food production industry.
3. **Advantages of Food and Beverage Reverse Osmosis Equipment:**
(1) Reverse osmosis equipment is designed with a recovery rate of over 75%.
(2) There is low-pressure protection for reverse osmosis water, preventing the high-pressure pump from running dry.
(3) The reverse osmosis system operates automatically and will refresh itself after one hour of continuous operation.
(4) Pre-treatment regeneration and backwashing of the reverse osmosis system will automatically shut down, with the raw water pump automatically starting.
(5) When the pure water tank is full or the raw water tank is empty, the reverse osmosis machine will automatically shut down. When the pure water tank is low, the reverse osmosis machine will automatically start.
(6) Fault alarm signals are set up.
(7) The built-in PLC has indicator lights, making maintenance easier.
