The water used for food production must strictly comply with the special production specifications, and there are no visible impurities, no odors, heavy metals, and the total number of colonies.Segmented scenarios such as beverages, dairy products, sauces, baking, etc. have more stringent requirements for water purity. Ordinary multi-stage filtration simply cannot meet the bottom line. Customized food-grade pure water equipment must be used for deep purification in order to meet the red line of product compliance from the source.
The selection should fully match the scale of production, and it should not be blindly greedy for completeness: the average daily water consumption of small baking workshops and sauce workshops is small, and the 1-5T/H single-stage reverse osmosis pure water equipment completely covers the needs of ingredients, bottle washing, and equipment cleaning, which is cost-effective and has a very low threshold for operation and maintenance; large-scale beverage industrial parks and dairy factories require 24-hour continuous water supply, and must be equipped with 5-20T/H two-stage reverse osmosis pure water equipment with stable desalination rate and full capacity, strong water quality resistance to fluctuations, and adaptable to large-scale continuous production conditions.
Pure water equipment
The selection of food-grade pure water equipment must be stuck with three core red lines：
Material compliance: All wading and overcurrent parts are made of food-grade 304/316 stainless steel, and ordinary carbon steel must not be used to prevent long-term operation of rust chips from precipitating and polluting water bodies.
Adapt to local water quality: In view of the high hardness and high sediment characteristics of Xi'an raw water, the front must be equipped with a softening + multi-media filter combination to avoid fouling and blocking of the RO membrane within 3 months.
Priority is given to local physical manufacturers: refuse to subcontract layers of middlemen to ensure that installation and commissioning, emergency repair of faults, and replacement of consumables come to the door within 4 hours, and there will be no after-sales situation where no one can be found.
A medium-sized beverage factory in Weiyang, Xi'an, previously used a general simple water purification equipment. The water quality of the effluent fluctuated from high to low, and the finished product occasionally showed unknown precipitation and odor, and faced the risk of unqualified sampling at any time.The DIEN team came to the door to take water for testing in three consecutive days, and customized the integrated 5T/H food-grade pure water equipment of “pretreatment softening + two-stage reverse osmosis + ULTRAVIOLET sterilization + ozone preservation”, and the whole pipeline was mirror polished without sanitary dead ends.After being put into operation, the conductivity of the effluent was stable within 2µs/cm, the total number of colonies was not detected throughout the process, the product precipitation odor problem was completely cleared, and the fully automatic operation did not require special personnel on duty, and the annual operation and maintenance cost was reduced by 35%.
As a local source entity manufacturer in Xi'an, DIEN Water treatment, all food-grade pure water equipment is customized on demand, rejecting general low-profile models and hard-set working conditions, the whole process quotation is transparent and there is no invisible consumption, and the whole territory of Shaanxi responds to after-sales within 2 hours to help Xi'an food companies steadily maintain the bottom line of production water compliance.
