Description

Description: TECHNICAL FIELD The present invention relates to a beverage filling line cleaning device for cleaning the equipment and piping of a beverage filling line in place.

(Prior Art) FIG. 2 shows an example of a conventional cleaning device for a beverage filling line including a stationary cleaning device and a device to be cleaned. In Figure 2 15
0 indicates a stationary cleaning device (one example). Here, the cleaning liquid, the sterilizing liquid and the rinsing liquid are collectively referred to as a processing liquid. The cleaning liquid and / or the sterilizing liquid is stored in the cleaning liquid tank 158,
If necessary, the solution is delivered to the equipment to be cleaned by the cleaning solution delivery pump 156 through the tank outlet valve 159. The cleaning liquid is heated by the heating device 157 if necessary.

Liquid storage tank 152, liquid treatment device 153, filling machine for equipment to be cleaned
154 are connected in series by a liquid supply pipe 151 for supplying a cleaning liquid. In addition, a pump 155 for sending the cleaning liquid to the downstream equipment to be cleaned is installed in the middle of the liquid supply pipe 151. The cleaning liquid returned to the stationary cleaning device 150 by this pump 155 passes through the recovery valve 160 and the cleaning liquid tank 158.
Or discharged from the drain valve 161. The tank outlet valve 159, the cleaning liquid delivery pump 156, the heating device
157, the recovery valve 160, the drain valve 161, and the pump 155 are automatically controlled by a control device (not shown).

By the way, the stationary cleaning device 150 continuously or intermittently supplies the cleaning liquid at a constant flow rate by the cleaning liquid transfer pump 156 in a predetermined order and time by a controller (not shown). Further, the cleaning liquid is supplied to the pump 15 while cleaning the inner surfaces of the liquid storage tank 152, the liquid processing device 153, and the filling machine 154.
5 etc. through the liquid delivery pipe 151 to the downstream storage tank 15
2. Liquid is sent to the liquid processing device 153 and the filling machine 154. Then, the cleaning liquid that has cleaned the equipment to be cleaned such as the liquid storage tank 152 and made one cycle is returned to the stationary cleaning device 150 through the liquid supply pipe 151 and is collected in the cleaning liquid tank 158 by the recovery valve 160 or by the drain valve 160. Is discharged.

(Problems to be Solved by the Invention) Since the equipment to be cleaned is connected in series by the liquid supply pipe 151, the equipment to be cleaned on the upstream side is cleaned, or the rinse rinse liquid contaminated by rinsing is replaced by the equipment to be cleaned on the downstream side. Will be sent to
There is a problem that the cleaning and rinsing properties are worse in the downstream equipment to be cleaned and the cleaning and rinsing time is longer. In addition, since the equipment to be cleaned is connected in series, the cleaning liquid to be fed is mixed with the liquid stored in the liquid feed pipe in the equipment to be cleaned, diluted, and then sent downstream to be mixed in the same manner. Since the dilution is repeated, there is a problem that the amount of the cleaning liquid that can be collected and reused in the cleaning liquid tank 158 becomes small. Further, when performing heat cleaning sterilization, since the equipment to be cleaned is connected in series, heat is taken by the equipment to be cleaned upstream, and the cleaning liquid having a lowered temperature is sent to the downstream. How about
There is a problem that it takes time to raise the temperature to the specified temperature for heat sterilization.
