Problems solved by technology

This method can well deal with the impurity components dissolved in the solution during the cleaning process, but the solution in the storage tank may precipitate out a variety of mixed solution components during the long-term storage process, which cannot be solved by CIP cleaning first and then reflux filtration Impurities in the cleaning solution cannot overcome the failure of nozzle clogging in the CIP system

Embodiment 1

[0031] Taking the operation status of a single filter mechanism as an example, the CIP system automatically and sequentially starts clean water flushing, acid flushing, clean water flushing, alkali flushing, clean water flushing, and disinfectant flushing. First, the gate of the clean water storage tank 3d is opened, and the gates before and after the first filter mechanism 2a are opened, and the clean water in the storage tank is pumped to the first filter mechanism for filtration, and then the equipment to be cleaned is rinsed. Rinse for 5 minutes. Then close the gate of the clean water storage tank 3d, open the gate of the acid storage tank 3a, and rinse the equipment with acid solution for 3 minutes. After the pickling is completed, rinse with clean water again. The solution after washing the equipment can be directly discharged into the sewage pipeline. If the clean water after washing the equipment is relatively secondary, it can be returned to the clean water storage ta...

Embodiment 2

[0034] Such as figure 1 As shown, the CIP filtration and washing of the middle large system: open the gate of the pickling tank to let the pickling liquid flow out. A second pump pressurizes the pickling liquid and enters the equipment 1a, 1b, 1c to be cleaned to realize the flushing of the equipment. The solution for washing the equipment flows out from the liquid outlet at the bottom of the equipment, and then passes through the return branch under the pumping action of the return pump, and returns to the pickling tank; the pickling solution flushing time is 3 to 6 minutes, and the gate of the pickling tank is closed . Open the gate of the clean water storage tank, the clean water flows through the first pump, the filter screen, the second pump, and the equipment to be cleaned in sequence, and finally flows out from the liquid outlet at the bottom of the equipment, and is pumped by the return pump and discharged through the drainage pipeline ( figure 1(not marked in ), aft...

Abstract

The invention discloses a filtration washing method for a clean in place (CIP) central control system of a dairy product production line. The filtration washing method for the intermediate CIP large scale system comprises the following steps that (1) an acid pickling tank gate is opened, acid pickling solutions flow out and pass through a filter screen under the action of a first pump, then a second pump behind the filter screen pressurizes the acid pickling solutions, and the acid pickling solutions enter equipment to be washed to achieve flushing of the equipment; (2) the solutions for flushing of the equipment flow out from a solution outlet in the bottom of the equipment and then are pumped back into an acid pickling tank through a top return pump; and (3) an alkali washing tank, a disinfectant storage tank and a clear water storage tank are further arranged and share pipelines and the filter screen with the acid pickling tank. The clear water storage tank, the alkali washing tank, the clear water storage tank, the disinfectant storage tank and the clear water storage tank are opened in sequence to repeat the washing solution process in the step (1), and therefore alkali washing, disinfecting and flushing of the equipment to be washed are achieved. The clear water storage tank is repeatedly used, and it is guaranteed that various washing solutions do not interfere one another in the process of acid pickling, alkali washing and disinfecting.

Description

technical field [0001] The invention relates to a method for filtering and washing an intermediate system, in particular to a method for CIP filtering and washing an intermediate large system. Background technique [0002] CIP cleaning is CLEAN IN PLACE (cleaning in place), which can realize a safe and automatic cleaning system through simple operation without disassembling the production equipment, and is widely used in the food, beverage and pharmaceutical industries. [0003] At present, the cleaning pipeline of the CIP line of the dairy production line is directly connected to the filter equipment, and the solution in the acid tank, alkali tank and disinfection tank of the CIP system is directly pumped to the setting to be cleaned, and then returned after cleaning to the original storage tank. After a period of use, a certain amount of solid sedimentation residue will accumulate in the storage tank. These solid sedimentation residues are repeatedly circulated in the pip...
