How to Build an Air Energy High Temperature Heat Pump Drying Room

At present, the drying equipment used in the market uses air energy for heating and drying. The air energy drying equipment can not only operate unattended with one click, but also intelligently control the temperature, humidity, and time, accurately controlling the drying curves of the items to be dried at different stages. The equipment can be used normally for more than 10 years, making it the most ideal energy-saving drying method under strict national environmental protection requirements. It is 75% more energy-saving than direct electric drying, 40% more energy-saving than burning oil, and 30% more energy-saving than burning coal. It is currently the highly recommended drying method in various drying industries.
The scale depends on different situations
The scale of the drying room is generally determined based on the physical properties of the product, the output of the product, and the on-site land conditions. In the design process of a drying room, the land area is generally fixed, so the size of the drying room can only be within this area range, and different products should be treated differently. Example: An 8.5 × two point eight × A 2.2 meter flower drying room can normally dry 2000 kilograms of flowers at once, but for tea cakes of the same weight, only a half size drying room is required. The flowers themselves have a relatively large volume and are much lighter in weight compared to products of the same volume, so the scale of the flower drying room is required to be larger compared to other products. Before the construction of the drying room, we will select specific products for testing in the testing room, using the test data as support, so that the scale of the built drying room is suitable, without causing space waste or affecting the expected drying effect
Selection of building materials and modular construction
In terms of material selection for drying room construction, in order to facilitate the sealing and insulation of the drying room, the surrounding walls of the drying room are constructed in the form of double-layer color steel with 10cm foam sandwiched in the middle. Due to the fact that the drying room also undertakes the function of product transportation, workers often use carts for repeated transportation. In order to ensure the service life of the drying room, the ground is usually constructed with the same material as the wall, and an additional 3-5 mm stainless steel plate is laid. This can avoid uneven ground caused by long-term heavy pressure and also ensure the work efficiency of the transportation workers.
In the construction process of the drying room, modular construction is required. If a 40-60 square meter drying room project can be divided into two 20-30 square meter modules, and the construction of one module requires approximately one technician and two laborers, which takes five hours and labor costs approximately 500 yuan. Therefore, the total construction cost of the entire project is 1000 yuan. As a whole, considering the orderliness and completeness of the engineering process, the number of on-site construction personnel will greatly increase, while also wasting a lot of time, with a cost of over 3000 yuan. It can be seen that modular construction has a good effect in reducing construction costs.

Setting of single and double row drying racks
Generally, it is determined based on the size of the drying room and the physical properties of the product, and there are two forms: single row and double row. Double row drying racks should be constructed along the long side of the room, while single row drying racks should be placed on the long side or in the middle position. The drying rack used is generally 0.8-1M, with a height of 2-2.5M. The lowest layer is at a height of 10-20C, and there is one layer every 8-15CM upwards, with a total of 6-15 layers. For products with large volume, the spacing between each layer is large, while for products with large weight, the number of layers is appropriately reduced. Mr. Wang also proposed that regardless of the single row or double row style, the inner wall of the baking room should be smooth and clean, sealed and airtight, and appropriate space should be reserved for personnel walking, product transportation, and equipment operation.
Choose efficient and intelligent heat pump drying equipment
When selecting air drying equipment, factors such as dehumidification capacity, heat recovery capacity, ease and intelligence of operation, and uniformity of hot air must be considered. Equipment with strong dehumidification and heat recovery capabilities can reduce equipment operating energy consumption and improve product quality. The intelligent and simplified operation panel can achieve one click switching under different control modes, without the need for personnel supervision. It can not only meet the different needs of users, but also allow ordinary people to operate under simple training, improving usage efficiency and reducing labor costs. At the same time, the equipment optimized by the system can improve the uniformity of drying, ensure uniform product quality, and thus achieve higher economic benefits. Guangdong Hepai manufacturer provides two types of air drying equipment: integrated and split.
In addition, for the selection of machine models and equipment installation issues, it is necessary to choose the overall machine as much as possible to maintain a close structure between the equipment and the drying room. During the installation process of the drying equipment, the specific installation position of the equipment should be determined based on the specific location of the drying room and the degree of close integration with other factories. At the same time, try to install the equipment host inside the drying room and the external fan outside the drying room to avoid equipment insulation problems caused by weather and seasonal changes, thereby reducing labor and financial costs.
