Product Overview
Fully automatic CIP (Cleaning In Place) refers to the cyclic cleaning of equipment (tanks, pipelines, pumps, valves, etc.) and the entire production line in a closed circuit, without manual disassembly.
This system adopts a split independent tank layout, configured with a PLC programming control system and color touch screen operation panel, which intuitively displays the full process flow and all operating parameters. Cleaning temperature, tank pH value, cleaning duration, cleaning sequence and return pH value can all be freely set, with a built-in system fault alarm device. The system supports customized multi-circuit configurations and multiple heating methods, delivering standardized and traceable cleaning processes. It serves as core supporting equipment for medium and large food and pharmaceutical production lines to achieve hygienic compliance and automatic operation and maintenance.
Equipment Features
- Full-process automatic operation PLC control paired with color touch HMI enables presetting of all parameters including cleaning temperature, acid-base concentration, time and sequence. The whole process runs automatically without manual attendance, ensuring stable and traceable cleaning performance.
- Parallel multi-circuit operation Customizable dual-circuit, triple-circuit or four-circuit configurations are available. Multiple cleaning zones can work simultaneously, and cleaning can be performed during production, greatly reducing production line downtime.
- Automatic accurate concentration compensation The system automatically detects the concentration of acid and alkali solutions in the tank, and automatically supplements concentrated acid/alkali via diaphragm pumps, stabilizing cleaning efficiency while reducing reagent waste and operating costs.
- Flexible split layout Each cleaning tank is designed as an independent split unit, which can be flexibly arranged according to workshop space, adapting to different plant layouts and facilitating subsequent production line expansion and transformation.
- Optional heating solutions Heating methods include plate type, coil type and tubular heat exchangers, which can be flexibly selected according to on-site heat source conditions, featuring high heat exchange efficiency and uniform liquid temperature rise.
- Comprehensive safety assurance Equipped with a system fault alarm device, it automatically warns of abnormal liquid level, temperature and pressure, ensuring stable equipment operation and production safety.
- Fully enclosed sanitary design The entire cleaning process circulates in a closed circuit to avoid secondary pollution. The whole machine is made of food-grade stainless steel, complying with hygienic production standards of food and pharmaceutical industries.
Working Principle
The system mainly consists of CIP cleaning solution storage tanks (acid tank, alkali tank, hot water tank, clean water tank), CIP feed pump, CIP return pump, concentrated acid/alkali diaphragm pumps, heat exchanger (plate / tubular type), control valve group and electrical control cabinet.
During operation, the cleaning solution is pressurized by the feed pump, accurately adjusted to the set temperature through the heat exchanger, and then delivered to the inner cavities of tanks, pipelines and equipment to be cleaned, circulating continuously in the closed circuit. Through the physical scouring effect of high-speed liquid flow combined with the chemical decomposition effect of acid and alkali solutions, material residues, organic dirt and microorganisms on the inner wall of the equipment are completely removed.
The waste liquid after cleaning flows back to the corresponding storage tank via the return pump. The system automatically detects the pH value and temperature of the return liquid, automatically supplements concentrated acid/alkali and adjusts heating power as needed to continuously maintain cleaning efficiency. The whole process requires no equipment disassembly or manual intervention, and completes full-process cleaning in closed pipelines.
Standard Process Flow
- Pre-rinse Clean water is injected into the cleaning circuit to flush out most loose material residues, and the waste liquid is discharged after completion.
- Alkaline solution cyclic cleaning The alkaline solution is heated to the set temperature and circulates in a closed circuit to decompose organic dirt such as grease and protein. The alkaline solution is recycled back to the storage tank after cleaning.
- Intermediate water rinse Clean water is introduced to flush residual alkaline solution in the pipeline, avoiding acid-base neutralization that affects the subsequent acid washing effect.
- Acid solution cyclic cleaning The acid solution is heated to the set temperature and circulates in a closed circuit to remove inorganic dirt such as mineral deposits and scale. The acid solution is recycled back to the storage tank after cleaning.
- Final water rinse Clean water / hot water is introduced for final flushing to remove residual cleaning solution, and the process ends when the cleanliness of the return liquid meets the standard.
- Disinfection process (optional) Hot water or disinfectant is introduced for cyclic disinfection to kill residual microorganisms in the pipeline, and the pipeline is emptied after completion.
