Embodiment 1

[0027] In the fresh milk No. X canning workshop, the CIP cleaning method technique of the present invention is implemented on the production line A, and the process flow is as follows figure 2 As shown, pickling is not carried out after alkaline cleaning. The specific description is as follows: applications such as figure 1 In the shown CIP cleaning equipment system, after the canned production work on Monday, the CIP cleaning equipment is turned on, and the solution in the pre-rinsing tank 1 is used to pre-wash the equipment 9 on the production line in sequence, and the pre-rinsing solution is exhausted at the end of the valve. 5 Discharge into the waste water tank, observe the turbidity of the pre-flush solution at the discharge outlet, and stop the pre-flush when the solution is not obviously turbid. Then, start the alkaline cleaning process in the CIP cleaning equipment, and use the 2% alkaline solution in the alkaline cleaning tank 2 to perform alkaline cleaning on the ...

Embodiment 2

[0031] Similar to Example 1, on the unified production line, after finishing the canned production on Wednesday, the production line is cleaned by CIP, and the pre-rinsing and alkali cleaning steps described in Example 1 are completed first, and then the CIP cleaning program is adjusted so that the CIP cleaning The 1.8% nitric acid solution in the pickling tank in the equipment enters the pipeline of the CIP flushing equipment and is circulated for 30 minutes. After completion, clean water is used for final flushing (final flushing) of the filling equipment, and the circulation line of CIP flushing is set so that the flushing liquid is circulated back to the pre-rinsing tank or the return tank. Improve the sanitation of tanking lines by preventing the growth of alkali-resistant microorganisms through regular pickling every Wednesday.

[0032] Preferably, after the pickling is completed, the concentration of the nitric acid solution in the pickling tank is adjusted, and repleni...

Embodiment 3

[0034] In the fresh milk canning workshop X of the new factory, adjust the CIP cleaning procedure of the filling machine part on the production line A. Realization includes steps such as pre-rinsing, alkali washing, intermediate washing, pickling, and final washing. The water for the pre-flushing in the control comes from the recovery water tank, and the water for the final flushing comes from the clean water tank. In the process of pre-flushing, the flushing water is not recycled and discharged directly. When the water in the recovery water tank is insufficient, the water in the clean water tank is used for flushing. Experimental research adjusts the CIP data of the filling machine, optimizes the pre-flush time, and then tracks and verifies the optimized pre-flush parameters to ensure the cleaning effect of the filling machine. Finally, the verified optimized parameters were confirmed, and the pre-flushing of the filling machine was performed according to this parameter. The...

Abstract

The invention discloses a CIP (Clean in Place) cleaning method. The CIP cleaning method comprises the following steps of (1) opening CIP cleaning equipment, pre-flushing equipment to be cleaned with a solution in a pre-flushing tank, wherein the pre-flushing solution is directly drained, observing the turbidity the pre-flushing solution at a drainage opening, and when the solution does not have obvious dirty substances, stopping pre-flushing; (2) performing caustic washing on the equipment to be cleaned with an alkali solution in a caustic washing tank; and (3) after the caustic washing is completed, flushing the equipment with clean water, and enabling a solution obtained by flushing with the clean water to circulate to the pre-flushing tank for standby application. According to the CIP cleaning method disclosed by the invention, the pre-flushing solution in the flushing process is not recovered circularly, and is drained directly, most of dirty substances need to be removed through flushing with the pre-flushing solution, and the pre-flushing solution is directly drained, so that a good pre-flushing effect can be achieved, and the pre-flushing efficiency is improved.

Description

technical field [0001] The invention relates to the field of food, in particular to a CIP (Clean in Place) cleaning method. It is especially suitable for the CIP pre-flushing method applied to the filling machine. Background technique [0002] In the existing technology, the existing CIP cleaning scheme is mainly aimed at the highly closed food filling production line, to realize the comprehensive cleaning treatment of the equipment in each link of the production line, to avoid any residual pollution source in any part of the production line, and to damage the food. The quality of the filling. Generally speaking, the use of CIP cleaning has important advantages, because most of the food filling machines are closed equipment and instruments, which are not easy to disassemble and clean. CIP cleaning can use the turbulent cleaning liquid in the system to wash the equipment in sequence without disassembling the equipment, so as to achieve the purpose of fast and efficient clea...
