Sterile hot air system for filling machine

Abstract

The invention discloses a sterile hot air system for a filling machine, relates to filling machines, and aims to solve the problems that temperature control is unstable, and the quality of a beverage is affected due to the fact that air in a filling chamber does not exchange with the outside for a long time and is too turbid. According to the technical scheme, the sterile hot air system for the filling machine is characterized by comprising an air inlet box, an exhaust fan, a vertical pipeline, a horizontal pipeline and an air outlet box, wherein the air inlet box is provided with a coarse filter screen; the vertical pipeline is provided with a multi-stage air treatment assembly, and the multi-stage air treatment assembly comprises an impurity blocking device, a first-stage air heater, a second-stage air heater and a deep sterilizer; the horizontal pipeline is provided with a temperature probe; and the air outlet box is provided with a fine filter material. According to the sterile hot air system for the filling machine, real-time updating of the air in the filling chamber is realized, the stability of the temperature in the filling chamber is improved, and the cleanliness of hot air is ensured to meet the food sanitation requirement.

Description

technical field [0001] The present invention relates to filling machinery, more specifically, it relates to a kind of aseptic hot air system for filling machinery. Background technique [0002] The filling machine is the equipment used for beverage packaging. During the specific work, the film supply device provides the film. The film passes through the hydrogen peroxide sterilizing device and enters the central filling tube, and then the central filling tube winds the film to complete the roll. The wound film is sealed on both sides by the vertical sealing electrode, and the bottom is sealed by the horizontal sealing electrode. Finally, the beverage is poured into the film by the central filling tube. [0003] The filling process of the film is completed in the filling room of the filling machine. Some beverages have certain requirements for the temperature in the filling room when filling. Generally, a steam heat exchanger is installed in the filling room. In practice, it...

Problems solved by technology

[0006] By adopting the above-mentioned technical solution, when the present application is working normally, the air pressure generated by the exhaust fan is used to extract the external air, and the external air passes through the air inlet box, the vertical pipeline and the horizontal pipeline in sequence under the action of the air pressure difference, and finally the The air outlet box is blown out and enters the filling chamber; when the outside air passes through the air inlet box, the large particles of impurities and mosquitoes are blocked by the coarse filter, so that the first filter is realized on the premise of ensuring the smoothness of the air intake; completed The first-pass filtered air enters the multi-stage air treatment assembly. In the process of passing through the multi-stage air treatment assembly, the air is heated by the first-stage air heater and the second-stage air heater to complete the temperature increase and heat sterilization. The sterilizer further completes the sterilization and further improves the cleanliness of the air. Part of the dust and impurities generated by the two sterilizations may overcome the airflow and fall, and the impurities blocker picks up this part of the impurities to prevent the impurities from entering the vertical pipeline. The connection with the exhaust fan leads to the problem that it is not easy to clean. It needs to be explained here that the multi-stage air treatment components are arranged in the vertical pipeline, so that the forward trajectory of the air is vertically upward, so that the rising hot air can be used. The principle makes it easier for the airflow to enter the air outlet box, and improves the aerodynamic force of the hot air blown out of the air outlet box, and then spreads to the filling room better; when the heated and sterilized air enters the horizontal pipeline, the temperature is monitored by the temperature probe. And control the power of the primary air heater and secondary air heater according to the monitored temperature, so as to realize the control of the temperature of the blown air, and then improve the temperature stability in the filling room; before the hot air is finally blown out through the air outlet box, the The fine filter material is used to filter, so as to ensure the cleanliness of the hot air blown into the filling room; in summary, this application adopts the method of introducing hot air to control the temperature in the filling room, so as to realize the real-time monitoring of the air in the filling room. Update and monitor the temperature of the imported hot air to improve the stability of the temperature in the filling room, and ensure the cleanliness of the hot air to meet food hygiene requirements through multi-channel filtration and multi-channel sterilization
