Device Characteristics

1) Double deck tunnel pasteurizer with wire mesh conveyors，specially for beer pasteurizing, also capable as a warmer for draft beer. The machine housing and wire meshes are made in stainless steel（except working platform and steam piping）.

2) Driven by high torque and low-revolution variable motor characterizing by its low electricity consumption, gentle movement, safe and reliable operation.

3) The spraying system with cascade-like water distribution covering a wide range of area. The nozzle clogging defensible, well-proportioned temperature in each zones, bottle breakage minimized, perfect pasteurization guaranteed.

4) Low level (machine bottom) circulation piping system  well utilize the heat source to thus save the energy, water overflow caused by interruption of the pump is minimized resulting in low water consumption and low operation cost.

5) Conveyor belt is designed according to customer requirement, to be made by stainless steel or wearable plastic.

6) Drive for the wire mesh conveyors: the conveyors on the 1st and 2nd deck are driven individually by the frequency controlled motors with overload protection device and system is characterized by its simple control design, reliable operation and variant regulation.

7) The frequency controlled main variable drive. PU value control is realized on the multi-functional man-machine interfaced operation panel with display of process parameters, dot matrix graphs, graphs of various forms. Data processor equipped with printer functions machine operation, malfunction message handling, information and process value recording and storing, which is linked to the integrated interface of various controllers with communication modular, network connection is applicable to various protocols.

8) Easily controlled operation panel with malfunction message and operation status display: finely assembled control cabinet ensures reliable operation.

9) When the containers get jammed up on the conveyors , the main drive automatically stops running. There are 2 controlling options for the customer. A, The temperature value of the superheat pasteurization zone is automatically regulated according to the calculation formula of PU value, and cool water spraying system in the superheat, pasteurization zones are then actuated instantly and cool the temperature by cool water spraying  down to the adjusted degree, easing the abnormal PU increase caused by machine stop; B, Stop spraying in high temperature zone and pasteurizing zone, let the spraying water goes back to the tanks where they were belonged to, thus lower the beer temperature in these 2 zones. By choosing this option, the consumption of water and steam is lower, but it is more difficult to control the PU.

10)The value of temperature and PU in each temperature zone indicated in the human-machined interface.

The value of temperature and PU in high temperature zone and pasteurization zone are noted and stored either.
