Description

Ovens for Tunnel Sterilization Dryers

technical field

The utility model relates to the field of food and pharmaceutical packaging machinery, in particular to an oven used for a tunnel type sterilization dryer.

Background technique

The high-temperature section of the tunnel-type sterilization dryer mainly uses hot air to exchange heat and cold with the medicine bottle, so that the medicine bottle can be dried, sterilized and depyrogenated at high temperature. In the existing tunnel-type sterilization dryer, there is a cavity, and a set of hot air circulation unit for sterilization and drying is arranged in the cavity, and the medicine bottle is transported through a conveying mesh belt in the cavity. The hot air circulation unit generates hot air and blows it to the conveying mesh belt. The medicine bottle is sterilized and dried during the transportation process from the bottle inlet to the bottle outlet. In order to achieve higher output, under the premise of ensuring the sterilization time, generally Make the high-temperature section longer and wider, and increase the width of the conveyor belt so that it can carry more medicine bottles at a time (the width of the conveyor belt can reach 1.2-2 meters).

However, when the width of the box body and the conveying mesh belt is too wide, the flow of hot air blowing to the medicine bottles is not uniform, so that the hot air near the return air channel has a fast flow rate, and the temperature of the medicine bottles rises quickly, while the heat near the middle of the conveying mesh belt The flow rate of the hot air is slow, and the temperature of the medicine bottle is slow, which leads to the extremely uneven temperature rise of the medicine bottle on the conveyor belt, so that the medicine bottle near the return air channel on the conveyor belt has been sterilized, and the medicine bottle located in the middle of the conveyor belt However, the sterilization effect is still not achieved. In order to meet the sterilization requirements of the medicine bottle in the middle of the conveyor belt, the transmission speed of the conveyor belt can only be reduced, and slowing down the speed of the conveyor belt will make the medicine bottle in the unit time Yield is reduced.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art, and provide an oven for a tunnel-type sterilizing dryer with more uniform flow of hot air, easy control of air volume and speed, and high production efficiency.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

An oven for a tunnel-type sterilization dryer, comprising a box body, the box body is provided with more than two chambers arranged in parallel, and each chamber is equipped with a material conveying assembly and a hot air circulation unit.

As a further improvement of the utility model:

The hot air circulation unit includes a negative pressure suction chamber, a high temperature sterilization chamber, and a return air channel that are arranged in the chamber and communicate with each other to form a hot air circulation loop. The connection between the return air channel and the negative pressure suction chamber A heater is provided, and the negative pressure air suction chamber communicates with the high temperature sterilization chamber through more than one set of air supply components consisting of a hot air blower, a wind cover and a filter.

The material conveying assembly includes a conveying mesh belt, and the conveying mesh belt is passed through a corresponding high-temperature sterilization chamber.

Compared with the prior art, the utility model has the advantages of:

The utility model is used for the oven of the tunnel type sterilization dryer by setting more than two chambers in the box body, and setting a conveying component and a hot air circulation unit in each chamber, so that the medicine bottle can be transported to more than two chambers And dry and sterilize independently in each chamber. At this time, the width of the two chambers and the feeding assembly can be designed to be narrow to meet the requirements of high output. After the width of the chamber and the feeding assembly is narrowed , the fluidity of the hot air generated by the corresponding hot air circulation unit is also more uniform, so that the sterilization effect of the medicine bottle on the feeding assembly is better, the speed is faster, and the production efficiency is also higher.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Figures 1 to 3 show an embodiment of the utility model for the oven of the tunnel sterilization dryer, including a box body 1, and the inner cavity of the box body 1 is separated by an upper partition 4 and a lower partition 5 Two tunnel-like chambers 11 are formed. The two chambers 11 are arranged in parallel and symmetrically relative to the center line of the box body 1. Each chamber 11 is provided with a set of material conveying components 2 and a set of hot air circulation unit 3 , when working, the hot air circulation unit 3 in the two chambers 11 is independently controlled without interfering with each other, and the medicine bottle is conveyed by the feeding assembly 2 through the corresponding chamber 11 and is dried and sterilized independently in the chamber 11, and Compared with the existing tunnel-type sterilizing dryer, the width of the two chambers 11 and the conveying assembly 2 can be designed to be narrower under the condition of satisfying the same output per unit time, and the width of the chamber 11 and the conveying assembly 2 After the width is narrowed, the fluidity of the hot air generated by the corresponding hot air circulation unit 3 is also more uniform, the sterilization effect of the medicine bottle on the feeding assembly 2 is better, the speed is faster, and the production efficiency is also higher. In other embodiments, More than three chambers 11 can also be arranged in the inner cavity of the box body 1 , the principle is the same as when two chambers 11 are arranged.

In this embodiment, the hot air circulation unit 3 in each chamber 11 is designed with reference to the existing tunnel type sterilization dryer, which includes a negative pressure suction chamber arranged in the chamber 11 and interconnected to form a hot air circulation loop Chamber 31, high-temperature sterilization chamber 32 and return air passage 33, and the connection of return air passage 33 and negative pressure suction chamber 31 is provided with heater 34, and negative pressure suction chamber 31 passes through four sets by hot air blower 35 1. The air supply assembly formed by the air cover 36 and the filter 37 is communicated with the high temperature sterilization chamber 32, and four sets of air supply assemblies are arranged equidistantly along the feeding direction of each chamber 11. As shown in Figure 1, the hot air circulation The power comes from the hot air blower 35, the hot air blower 35 inhales the hot air heated by the heater 34, and blows it into the wind cover 36 (the direction of the arrow in the figure is the flow direction of the hot air), and the wind cover 36 disperses the hot air blown out by the hot air blower 35. , and then flow out after being filtered by the filter 37, and blow to the feeding assembly 2 from the top of the feeding assembly 2, after exchanging cold and heat with the medicine bottle on the feeding assembly 2, the temperature of the hot air drops, and the hot air passes through the return air passage 33. Reach the heater 34 and circulate like this. In addition, a supplementary air port can also be provided at the position corresponding to the hot air blower 35 on the casing 1 to compensate for the air volume lost in the circulation.
