In all aspects of food processing, water is not the main raw material, but the most basic raw material. Therefore, for food processing enterprises, good water treatment equipment is particularly important. At present, there are about hundreds of water treatment equipment manufacturers in the market. How can we choose the best supplier of water treatment equipment? In this regard, the author recently visited many enterprises and exchanged with many industry experts. Through in-depth investigation and understanding, summarized the deionized water treatment equipment in the following aspects, hoping to help food processing enterprises choose water treatment equipment. First, safety first, access to qualifications for food enterprises, food safety is the top priority. Therefore, when choosing suppliers, food enterprises should first consider safety. Safety can be inspected from the following aspects: First, the safety of process and technology can ensure that the required indicators are met. For example, the effective removal of heavy metal ions and the control of microbial content. Secondly, the components of the equipment are safe, and no harmful leachate from the coating water treatment equipment is allowed. Because water treatment equipment will flow through various pipelines and filter materials from the inlet to the outlet, it is necessary to control the material quality of these pipelines and materials so as to avoid adding harmful secondary pollutants to the water.

Finally, the alarm system, when equipment fails, there must be an alarm system to avoid contaminated water into the food processing section. So, as a layman of water treatment, how can we judge the above three more professional points? It seems difficult, but what is it? Regarding the first two items, we can check whether the products of the manufacturer have the "Sanitary License for Aquatic Products" issued by the Ministry of Health to verify the safety of water equipment and pipeline materials for glass tank membrane cleaning. The Ministry of Health will have a perfect procedure to check the safety of parts and components as well as the safety of the whole machine function when checking the approval of the sanitary license for aquatic products. As long as the relevant batches are obtained, it can be basically confirmed that they are safe. The last alarm system is also very important. The automatic alarm and adaptive processing system produced by Beijing Inoglyn Technology Development Company can solve this problem well. Additionally, QS certification in the food industry is becoming more and more stringent. If the equipment purchased does not have the "Sanitary License for Aquatic Products" issued by the Ministry of Health, enterprises will encounter great trouble when they do QS certification in the future, and even need to re-purchase the equipment with certificates. 2. Configuration competition, beware of the configuration of trap water treatment equipment, because it is more professional, so it is trapped heavily. Pumps, because it is for food processing enterprises, so the material must choose stainless steel pumps.

For some low-power pumps, such as pumps below 10KW, experts believe it is necessary to choose imported pumps, such as domestic Southern special pumps and other manufacturers'products can fully meet the requirements. In terms of filter material, we must not only compare the price, but also the actual parameters of the filter material. For example, the price difference between iodine adsorption value 750 and 900 for the same activated carbon filter material is nearly double. Controller, small equipment can use Fleck or Runxin controller, but slightly larger (2T/H) equipment, because of the insufficient backwashing flow of the controller, experts recommend using Beijing Jiuzhou Science and Technology Development Company's full-automatic system, can solve the problem of insufficient backwashing. Regarding the choice of membrane, although there are many domestic membrane manufacturers, such as Huitong, Ander, etc., experts'suggestions are still in the choice of Dow and Hyde Neng brands, the quality is relatively stable. When an enterprise evaluates different suppliers, it must not only look at the price, because the water treatment equipment itself is a combination, so it must be compared and configured in detail item by item. In addition, it depends on whether the configuration is designed according to the actual situation of your enterprise, and whether it can meet the requirements of water quality and use. 3. On-the-spot investigation, many water treatment companies in Li Gui's market were eliminated, each of them said how big their enterprises were, how strong their strength was, and so on. What is the actual situation? According to the survey, although there are many water treatment products on the market, there are few large-scale processing capabilities. Most of them are not produced by themselves. After receiving the orders, they find some small workshops to process them. The products produced in this way are difficult to be trusted and the quality can not be guaranteed. According to our understanding, in the market, domestic enterprise management is relatively standardized and large-scale, such as Zhejiang Dow (formerly Europe and America), Beijing Bishui, Bluestar Group, etc., is trustworthy. Imported products such as GE, Siemens, 3M and other companies are reliable. In addition, in the industry, there are still many fake foreign enterprises, real domestic phenomenon, we must guard against! It is to register a bag company abroad, get a trademark, and pack it when you come back, that makes it a big international brand. In fact, these imported products are produced in small workshops and factories in China. Fourthly, the strength of the company and the guarantee of reputation are the most important factors to examine the strength of the company. If we evaluate the strength of the company from the following aspects, we should be more objective.
