1. Reflow outside the device
When the material is sterilized by UHT and sent to the filling machine, if the temperature of the material is lower than the set value T, the material is returned from the outer pipe of the valve V4 to the UHT to reheat and sterilize, effectively controlling the filling temperature. It is external reflow.
2. Reflow during filling
In the hot filling process, the filling state and stability of different materials are different, which affects the filling speed and is easy to produce half bottle phenomenon. The Baibo Rui filling machine generates a certain negative pressure through the exhaust fan, and quickly sucks away the air and foam in the bottle during the filling process, which not only improves the filling speed, but also solves the half bottle phenomenon, and is also effective. The bottle body bulging and material spillage caused by other filling methods are avoided.
3. Reflow in the filling valve without bottle
Downtime for various reasons during the filling process may cause a decrease in the temperature of the material in the upper cylinder and the valve.
At this time, the material of the return passage inside the filling valve can still flow according to the filling process at a certain flow rate, so that new materials are replenished in the upper cylinder and the filling valve to make the temperature of the material in the upper cylinder and the filling valve. Maintain the required range to achieve true hot filling requirements.
4. Control of return flow
Backflow control is a very important and critical technology for hot filling machines and is indispensable. Too much backflow will cause the material to be repeatedly heated and sterilized, causing changes in the taste and flavor of the beverage, and even affecting the inherent quality of the beverage. In the Baibo Rui filling machine, the return flow is controlled by the external valve opening cylinder on the filling valve, the valve closing cam, the exhaust fan and the electric control system. When there is a bottle, the valve is opened, and the external control rod is rotated to open the filling valve. After the material in the bottle reaches the required liquid level requirement, the valve closing cam closes the filling valve to stop filling; when the bottle is not in use, the cylinder does not move, and the filling The valve is not filled. Moreover, the valve closing cam can adjust the valve closing position according to the material characteristics and filling state, and truly control the return flow during the filling process.
