Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require the use of square vacuum dryers, it is recommended to prioritize confirming key technical parameters such as effective capacity and ultimate vacuum degree of the equipment to ensure compatibility with material processing capacity and process requirements. For example, the food industry often requires a vacuum environment of -0.095MPa or higher.
  • Square vacuum dryer is suitable for low-temperature drying of thermosensitive materials and is widely used in the pharmaceutical and chemical industries. When purchasing, the inner wall material (such as 304 or 316L stainless steel) and heating method (steam/electric heating) can be selected based on the material characteristics.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable equipment performance data.
  • In actual procurement, attention should be paid to whether the equipment structure design is easy to clean and maintain, especially for models used in GMP workshops, which should ensure no dead corners and be equipped with practical functions such as quick opening doors.

Knowledge Base

Q

Choosing a vacuum pump for a square low-temperature vacuum drying oven requires a comprehensive consideration of multiple factors. Firstly, consider the pumping rate of the vacuum pump, which should match the volume of the drying oven. Generally speaking, the larger the volume of the drying oven, the higher the required pumping rate, so as to achieve the required vacuum degree within the specified time. Secondly, attention should be paid to the maximum vacuum degree of the vacuum pump, which needs to meet the requirements of the drying process

Q

Square vacuum dryers are widely used in multiple fields. Due to its unique square structure, the material is heated more evenly during the drying process, improving drying efficiency and product quality. Mainly used for drying easily decomposable materials such as resins and pigments in the chemical industry; Dehydration treatment of dry goods in the food industry, such as shiitake mushrooms, black fungus, etc; And the sterilization and drying requirements for tablets and granular drugs in the pharmaceutical field. These applications fully demonstrate the efficiency and wide applicability of square vacuum dryers.

Q

Square vacuum dryers are mainly used in industrial production and laboratories for dehumidification, drying, and other processing of materials. It can create an oxygen free environment to prevent substances from getting damp or oxidized during the processing. The use of square vacuum dryers is very extensive and can be applied in many different fields. The following are its main uses: 1
