一． 设备简介

1、 Equipment introduction

食品纯水设备一般选用反渗透系统，主要应用于饮料、酿酒、奶制品、发酵、食品加工等行业，对水质的要求通常需要用到预处理净水或纯净水,电导率通常在10uS/cm以下。JDB电子水务在满足用户用水标准的基础上，在设备系统中水箱均设有液位控制系统、水泵均设有压力保护装置、在线水质检测控制仪表、电气采用PLC可编程控制器，真正做到了无人职守，同时在工艺选材上采用推荐和客户要求的方法，使设备与其它同类产品相比较，具有更高的性价比和设备可靠性。

Reverse osmosis system is generally used for food water purification equipment, which is mainly used in beverage, wine making, dairy products, fermentation, food processing and other industries. Pretreatment or purified water is usually required for water quality requirements, and the conductivity is usually below 10us / cm. On the basis of meeting the user's water use standard, Hongjie water has set up liquid level control system in the water tank of the equipment system, pressure protection device in the water pump, online water quality detection and control instrument, and PLC programmable controller in the electrical system, so that no one is on duty. At the same time, the method of recommendation and customer requirements is adopted in the process of material selection, so that the equipment is compared with other similar products, It has higher cost performance and equipment reliability.
