Pulsation control system for pulsation sterilizer and control method thereof

Abstract

The invention discloses a pulsation control system for a pulsation sterilizer and a control method thereof, and relates to the technical field of pulsation sterilizers. The system comprises a sterilizer body. A vacuumizing pipeline is arranged on one side of the sterilizer body, and a heat exchange pipeline is arranged on one side of the vacuumizing pipeline. In the invention, a novel control method is designed for a pulsation technology; the sterilizer body can be ensured to have operations of negative pressure pulsation, cross pressure pulsation and positive pressure pulsation at the same time; meanwhile, positive and negative pressure pulsation processes can be ensured; pressure is adjustable, the sequential pulsation is increased or decreased progressively; a pressure impact on the sterilizer main body due to great increase of the pressure is avoided; and once cross-pressure pulsation is carried out in the process so that multiple times of cross-pressure pulsation are avoided, theproblem of material fatigue strength caused by an alternating load borne by the sterilizer main body is reduced, a service life of the sterilizer main body can be prolonged, the safety performance ofthe sterilizer main body is improved, sterilization quality and temperature uniformity are guaranteed, and product sterilization performance is improved.

Description

technical field [0001] The invention belongs to the technical field of pulsation sterilizers, in particular to a pulsation control system and control method for pulsation sterilizers. Background technique [0002] At present, the pulsation technology only has pure positive pressure pulsation technology, pure negative pressure pulsation technology and pure cross-pressure pulsation technology. The pulsation technology used in traditional sterilizers has the following disadvantages: [0003] 1. The cold air in the inner chamber of the sterilizer is not completely removed, which will affect the uniformity of heat distribution in the later stage, which will easily cause the humidity of the loaded items to increase and affect the drying effect; [0004] 2. The degree of fatigue damage to the main body of the sterilizer is relatively serious, and the force distribution is unreasonable, which is easy to cause stress concentration corrosion, which reduces the conventional service lif...

AI Technical Summary

Problems solved by technology

[0003] 1. The cold air in the inner chamber of the sterilizer is not completely removed, which will affect the uniformity of heat distribution in the later stage, which will easily cause the humidity of the loaded items to increase and affect the drying effect;

[0004] 2. The degree of fatigue damage to the main body of the sterilizer is relatively serious, and the force distribution is unreasonable, which is easy to cause stress concentration corrosion, which reduces the conventional service life of the container to a certain extent;

[0005] 3. Increased energy consumption, large consumption of saturated steam, water and electricity;

[0006] 4. Poor penetration of saturated steam on lumens, fabrics, and other multi-cavity items, the effect is not ideal, affecting the sterilization balance time and the overall sterilization performance;

[0007] 5. The inner chamber of the sterilizer is directly returned to the air, which is easy to humidify the humidity of the items, and it is difficult to achieve the drying effect on the moisture inside the items.
