Improve heat energy utilization
Formally speaking, the boiling dryer is an air convection drying device, but there are still problems such as high energy consumption and insufficient equipment sealing.
The industry said that it can achieve good energy-saving effects by taking the following measures: Strengthen the sealing effect of the equipment. The original hopper of the boiling dryer is connected with the plane of the equipment by a flat flange, and the sealing effect is poor. After changing the flange connection of the concave and convex surface, the sealing of the hopper and the equipment body is better, and the heat insulation layer is added to the heat exchanger. The outer shell is provided with an insulating layer, and the thickness of the insulating layer is increased to greatly reduce heat loss.
Improved trapping dust removal device
The boiling dryer realizes the dust removing effect by the reciprocating motion of the cylinder to achieve the dust removing effect. The bag is made of anti-static and fiber-free cloth, and the collecting bag is in the form of integral lifting. The filter bag is connected by a clamp connection method, and the hanging rib is made of a rigid material that is not easily deformed, thereby effectively prolonging the life of the dust collection device and reducing maintenance.
Improved control system
The operating parameters of the boiling dryer are mainly set by the operator's experience, but they can be fully intelligent and traceable to the process parameters, which puts higher requirements on the electrical control system of the equipment. In the electrical control system, a series of devices such as temperature, pressure, differential pressure, and operating time are required to obtain basic data, which are transported and stored in the touch screen through the transmitter, and the data is stored and analyzed by the touch screen, and then a suitable one is developed. Intelligent routing can be achieved.
Temperature control
As we all know, the hot air heating control mode adopts a simple "on" and "off" mode. When the temperature reaches the set value, the steam is stopped, but the heat exchanger still has residual heat to keep the air temperature rising, and vice versa, which will cause the temperature. The fluctuation is too large, affecting the dry quality of the equipment.
It is recommended in the industry that the temperature signal can be changed and processed by PLC, the steam valve can be controlled to open and close, the temperature closed-loop control can be realized, and the self-control purpose can be achieved. The size of the steam flow valve can be controlled to maintain the inlet air temperature, and the steam starts to rise. The flow rate is large, so that the inlet air temperature is close to the set value as soon as possible, and then the steam quantity is automatically adjusted to slowly approach the set value, and the steady steam quantity is maintained to keep the inlet air temperature stable.
All in all, before improving the boiling dryer equipment, it is necessary to understand the working principle of such equipment, and then combine these principles with the technical problems in the production process to improve the equipment to meet the user requirements. It is announced that some improvements to the dust collector, temperature and air inlet filter device can better meet the production requirements and bring better production benefits for the production.
How to improve the boiling dryer to achieve greater benefits?
Boiling dryer is a common drying equipment, widely used in traditional Chinese medicine, food and other fields. However, in actual operation, some customers have reported that the boiling heat loss of the boiling dryer is large and the dust removal is difficult. The automatic temperature control system of the boiling dryer is controlled by the original instrument and relay. The heating temperature of the equipment during the use of the system The upper limit and the lower limit differ greatly, which is not conducive to production and other issues. So, how should we solve such problems and ensure that equipment is energy-efficient, stable, and achieve greater benefits?
