Heat pump business school drying class opens 100 billion heat pump to dry blue ocean market

The air source heat pump industry has entered a period of rapid development with the support of national policies. Not only has it developed rapidly on the heating road, but the air source heat pump drying field has also developed rapidly, becoming the next 100 billion blue ocean market. In view of this, sponsored by the industry's first media "Heat Pump Market", the domestic first-line professional brand New Entai sponsored the 19th heat pump business school drying class officially started on October 25th in Anhui Huangshan, focusing on the heat pump drying system. Design and transformation, through learning, let the students fully grasp the design of the new heat pump drying system, and systematically learn the method of heat pump drying system transformation.

This year's lecturer lineup is at the top of the line. It is the chief engineer of Guangdong New Entai New Energy Technology Development Co., Ltd., the heat pump expert group of China Energy Conservation Association, the energy conservation home appliance project of International Copper Association, the Li Yuan, School of Materials and Energy, Guangdong University of Technology, and the heat pump business school. The dry class special lecturer, the first-line practical expert hair flat, the heat pump business school drying class special lecturer, Zeng Guohui who specializes in the transformation of the baking room, the special lecturer of the drying class of the heat pump business school, and Song Benlin, the master of the chrysanthemum drying craftsmanship in China, gave lectures. This heat pump business school adheres to the principle of practical operation + technical introspection. The lecture focuses on the design and modification of the heat pump drying system. Through the study, the trainees fully grasp the design of the new heat pump drying system, and the system learns the heat pump drying system transformation. method.

Before the start of the class, Song Benlin gave a brief introduction to the types of chrysanthemum, water content and dehydration rate. Because of the swaying of the golden silk emerald, it is a pity that the gods are not beautiful, and the head flower of the golden silk queen is not in full bloom. The organizer has purchased a large number of July chrysanthemums for this purpose. . He emphasized that the process of picking, arranging, warehousing and drying the golden silk daisy will have an effect on its color, nutrition and flavor. It should be placed in a singular manner and cannot overlap. On the contrary, the pendulum of the July chrysanthemum is relatively simple, as long as it is uniform and cannot be stacked too thick. In accordance with the advice of Teacher Song, the trainees tried to make a one-piece material rack and carefully placed them neatly. Many students at the scene said that they can't do it, and only when they actually do it can they really understand.

The China Energy Conservation Association Heat Pump Expert Group, the International Copper Association Energy Saving Home Appliances Project, and the School of Materials and Energy, Guangdong University of Technology, Mr. Li Fan, lectured on “The Principle and Application of Heat Pump Drying”, which brought a vivid knowledge of heat pump drying at the scene. meeting. He elaborated in detail from the physical principle of heat pump drying to classification to design and future application prospects. The theoretical knowledge is combined with actual cases. Li Fan emphasized that as a drying distributor, it is necessary to grasp the relationship between the temperature, humidity and moisture content of the air. It is necessary to grasp the relationship between the equalizing line, the isotherm, the equal humidity line and the relative humidity line. Only by mastering these basics is it that only in the specific drying project can scientific unit selection be done, and a suitable set of processes can be matched among thousands of materials. After half an hour of technology sharing, many students consulted with Mr. Li.

Subsequently, the all-round drying expert Mao Ping, who combines theory and practice, shared the knowledge points that must be mastered in the heat pump drying industry from the principles and characteristics of heat pump drying, system design, installation and commissioning of drying. . Mr. Mao also elaborated the design of the drying room plan from his own experience, including the acquisition of the customer's demand parameters and the formulation of specific plans, and taught the students to design the drying system.

Mr. Zeng Guohui, the gold medal lecturer of the Heat Pump Business School, shared the topic of the drying and transformation project. From the current situation of the traditional drying room, the advantages of different drying rooms and the selection of the drying system, the trainees were taught how to carry out the transformation of the drying room system. Mr. Zeng not only explained the transformation of the drying system that replaced the traditional heat source, but also shared his own transformation case with the students in the case of the case. The students felt that they had gained a lot.

In the afternoon of the next day, the organizer arranged a chrysanthemum drying base to observe. This chrysanthemum drying project has 5 sets of 7.7x4.3x3.15 meters drying room, which is made of polyurethane material, 75mm thick double-layer color steel plate, hollow square steel pipe support. The top is a heated static warehouse, which is a positive pressure ventilation, the bottom insulation uses extruded plastic material, and the upper layer is laid with a cold shutter to achieve the insulation effect of the drying room. To achieve a single design principle, each set of drying room is equipped with a set of 10 dehumidification drying units, and equipped with high-efficiency heat exchange system, the average dehumidification capacity can reach 26 kg per hour, and 800KG fresh products can be placed at one time. The fan adopts 12 negative pressure fans, positive pressure ventilation preheating, negative pressure suction, fan dynamic frequency regulation to adjust wind pressure air volume, medium partition 50MM gap ventilation to solve the upper wind vortex stay problem, to achieve the best drying effect. The fans in the drying room mainly include main circulation fan, strong exhaust fan and air intake fan. When configuring, the air volume and wind pressure of the drying room must be calculated. The wind passes through the material, and the resistance of the turning causes the wind pressure and the air volume to decrease. When the drying room is designed, it should be treated as much as possible to reduce the wind rotation.

On the 25th and 26th, the two-day heat pump business school Huangshan practical class was successfully completed. This training class was praised by Nuen Thai, and the support of companies such as Tongyi, Meiyao and Jinxing, the students were full of dry goods. The sponsors also got a good brand display.
