What precautions should be taken when using special gas explosion-proof dryers in the food industry?

Demargo (Shanghai) Energy Saving Technology Co., Ltd. When using special gas explosion-proof dryers in the food industry, there are the following precautions:

Gas selection and safety
Special gases that meet the safety standards of the food industry, such as nitrogen, must be selected. Demargo specializes in the manufacture of compressed air purification equipment. Its products cover a variety of types and can provide equipment with different characteristics according to the needs of the food industry. It has professional technical support for the selection and use of special gases, and can ensure that the selected gases meet safety standards. Inert gases such as nitrogen have stable chemical properties and are not easy to react with food. They can effectively remove oxygen and prevent food from spoiling. At the same time, the company will strictly control the purity of the gas to prevent impurities from affecting food quality.

The concentration and pressure of special gases must be strictly controlled through precise monitoring devices. Demargo's products have advanced control technology that can monitor and automatically adjust gas concentration and pressure in real time to ensure that they are within a safe range, avoiding problems such as excessive concentration affecting food flavor or texture, and unstable pressure causing uneven drying.

Drying temperature and time control
Different foods have strict requirements on drying temperature. Demargo's drying equipment can accurately set the temperature according to the type and characteristics of the food. For example, when drying fruits, the temperature is generally controlled at 40-60℃. Through its advanced temperature control system, it can avoid excessive temperature that destroys the nutritional components of the food or causes the surface to burn, and prevents problems such as low drying efficiency and the growth of microorganisms due to low temperature.
Reasonable control of drying time is crucial to food quality. With rich experience and professional technology, Demargo can help users determine the best drying time through experiments and production experience to avoid insufficient moisture removal from food due to too short time, or excessive drying of food due to too long time, and loss of original taste and color. For example, the drying time of dried vegetables can vary from several hours to dozens of hours depending on the specific type of vegetables.

Equipment cleaning and hygiene
The internal structure design of Demargo's special gas explosion-proof dryer is easy to clean and meets the hygiene requirements of the food industry. After each use, users can follow the operating instructions provided by the company to thoroughly clean the drying chamber, conveying pipeline and other components. Food-grade detergents and high-temperature steam sterilization can be used to ensure that the equipment is free of impurities and prevent cross contamination.

The equipment material is made of non-toxic, odorless, and corrosion-resistant materials that meet food hygiene standards, such as stainless steel 304 or 316L, etc., to avoid the migration of harmful substances in the material into food and ensure food safety. This is also a reflection of Demargo's attention to detail and quality.

Explosion-proof safety measures
Although it is used in the food industry, explosion-proof safety is still critical. Demargo's equipment has good explosion-proof performance, using explosion-proof motors, explosion-proof electrical components, etc., to prevent gas explosions caused by electrical sparks from hardware, providing safety protection for the food production environment.

The company's equipment is equipped with reliable explosion-proof pressure relief devices and gas leak detection and alarm systems. When the pressure in the equipment exceeds the safety threshold, the pressure relief device can release the pressure in time; once a gas leak is detected, the alarm system will immediately sound an alarm, and the equipment will stop running and perform ventilation and other operations according to the preset program to ensure the safety of personnel and equipment.

Personnel training and operating specifications
Demargo will provide users with professional operator training, covering the working principle, operation method and safety precautions of special gas explosion-proof dryers, including equipment startup, stop, parameter adjustment, emergency handling, etc., to ensure that operators can operate the equipment skillfully and correctly, laying the foundation for the normal operation of the equipment and food production safety.

The company will assist users in formulating strict operating specifications and safety systems, requiring operators to strictly follow the regulations and strictly prohibit violations. For example, it is forbidden to open the drying chamber door during the operation of the equipment, and the operation process must be strictly followed when adding or replacing special gases to prevent gas leakage, etc., to ensure the safe and stable operation of the equipment through standardized operations, and to ensure the quality and safety of food production. In addition, Demargo has passed multiple certifications including QS certification and ISO9001 quality system certification. It is a national high-tech and specialized enterprise that can provide users with high-quality products and perfect pre-sales and after-sales services. It also has rich experience and professional team support in personnel training and operating specifications.
