The microwave vacuum dryer is a new type of high-efficiency drying equipment for pharmaceutical machinery engineering. Because there are a few, it replaces many drying products in drying equipment.
Microwave vacuum drying equipment
First of all, the microwave vacuum drying equipment does not require a heat transfer medium and has a rapid heating rate. Because the microwave vacuum drying equipment is electromagnetic heating principle, directly heated to the inside of the object, 1 KW of microwave energy can be heated to 80 °C in room temperature water within 3-5 minutes, the heating rate is generally beyond the reach of drying equipment, and Conventional drying technology improves ergonomics by more than four times.
Second, microwave vacuum drying equipment, heating evenly. This is a characteristic of microwave heating. It heats the material from the inside to the outside at the same time, so that there will be no puffing effect.
Third, it is easy to control and continuously automate production. The microwave power can be controlled instantly and the temperature can be adjusted between 40°C and 80°C.
Fourth, microwave vacuum equipment processing products have a long shelf life, can preserve the original flavor and nutrient composition of food, preserve the physiological activity of raw materials, enhance the functionality of health food, and increase the added value of agricultural products.
Common mold frame: an important tool on the construction site
In the construction site, we often see a variety of tools and equipment, one of the most common is the ordinary mold. As an important construction auxiliary tool, the common die frame has been widely used in the construction industry. This paper will introduce in detail the related issues of the common die frame, including its background, composition, assembly, use and maintenance.
A common mold frame is a formwork used for concrete placement, which is composed of profiles and accessories that can be combined into formwork of different shapes and sizes according to different needs. In the construction site, the ordinary mold frame is mainly used for the pouring of concrete structures such as walls, beams and slabs. Due to its characteristics of reusable, convenient assembly and low cost, ordinary die frames have become important tools in construction sites.
The basic components of a common mold holder include profiles and accessories. Profiles are usually made of steel or wood and are used to form the frame and support structure of the template. Accessories mainly include bolts, nuts, washers, latches, etc., used to connect and fix profiles to ensure the stability and reliability of the template.
The assembly process of the ordinary mold frame is relatively simple, but some details need to be paid attention to. First, it is necessary to determine the shape and size of the required template according to the construction drawings, and then select the appropriate profiles and fittings. In the assembly process, it is necessary to follow a certain sequence and steps,
