CIP cleaning system is short for cleaning in place, also called positioning cleaning, which means that the equipment and pipelines do not need to be disassembled or moved, using high-temperature and high-concentration cleaning solution to exert a strong effect on the device to clean the surface of the equipment and pipelines which contact with the material. As an automatic cleaning system that can be operated safely and easily without breaking down the production equipment, the CIP system has been introduced into all food, beverage and pharmaceutical factories.

The primary purpose of a CIP cleaning station is to remove product residues, bacteria, and other contaminants from processing equipment to prevent cross-contamination, maintain product quality, and ensure the safety of the final product. The system is designed to provide efficient and automated cleaning, reducing the need for manual labor and minimizing the risk of human error.

CIP cleaning system is widely used in beverage, dairy, sauce, fruit juice, wine and other liquid food and beverage production enterprises with a high degree of mechanization.

CIP systems are extensively used in food and beverage processing plants to clean tanks, pipes, filling equipment, and other processing machinery. Applications include cleaning and sanitizing equipment used for dairy processing, brewing, bottling, juice processing, and more.

Milk and Dairy Processing Industry: CIP systems clean and sanitize milking equipment, storage tanks, and processing equipment in milk and dairy farms and dairy processing plants. Efficient cleaning is essential to maintain the quality and safety of dairy products.

Juice and Beverage Processing Industry: It is used to clean and sanitize a variety of equipment and pipelines involved in juice processing, such as fruit and vegetable preparation machines, fruit juice and pulp-making machines, juice blending and pasteurizing/sterilizing system, juice filling and packing system.

Breweries and Distilleries Processing Industry: CIP systems are integral in breweries and distilleries for cleaning brewing kettles, fermenters, storage tanks, piping, and other equipment used in beer and spirits production.

1. Structural type: one-body type and split-body type.
2. Heating method: steam heating and electric heating.
3. Control mode: Manual control, semi-automatic control, fully automatic control.
4. Tanks number: three tanks type(acid tank, alkali tank, hot water tank), four tanks type(acid tank, alkali tank, hot water tank, pure water tank), five tanks type(acid tank, alkali tank, hot water tank, clear water tank, circulating water tank).
5. Pressure Lines/Cleaning circuit/loop: Single circuit, double circuit, three circuits, four circuits or five circuits or pressure lines.

—Cleaning Solution Tanks: These tanks hold the cleaning agents, such as detergents, sanitizers, and water. The solution is prepared according to the specific cleaning requirements of the equipment being cleaned, these cleaning tanks mainly include the following:

• Acid and Alkali tank: SUS316L, double layers and PU insulation thickness is 60mm, off-central agitator 36rpm, high/low-level meter, overflow port, bottom drain port, top concentrated acid and alkali dosing port, top return port, conductivity meter connector, sealed manhole, adjustable legs, side outlet, lifting lugs, sampling valve, digital show thermometer, volume from 500L-10000L.
• Hot water tank: SUS304, double layers with PU insulation, inner layer upper and lower head thickness3mm, out layer 2mm, and PU insulation thickness is 60mm, high/middle/low-level meter, temperature sensor, sealed manhole, adjustable legs, side outlet, lifting lugs, digital show thermometer, volume 500-10000L.
• Pure water tank: SUS304 stainless steel, single layer tank, high/middle/low level meter, sealed manhole, adjustable legs, side outlet, lifting lugs, digital show thermometer, volume 500-10000L.
• Circulating water tank: SUS304, double layers, high/middle/low level meter, sealed manhole, adjustable legs, side outlet, lifting lugs, digital show thermometer, volume 500-10000L.

–Heat Exchangers: The tubular or plate heat exchangers are used to heat the cleaning agent to 50-60℃.

–Pumps: Pumps are used to circulate the cleaning solution through the system at a controlled flow rate and pressure. They ensure that the cleaning solution reaches all the necessary areas and removes the contaminants effectively.

–Spray Devices: Spray devices, such as spray balls or nozzles, are installed in the equipment or pipelines being cleaned. These devices distribute the cleaning solution throughout the surfaces, ensuring thorough cleaning and sanitization.

–Control System: CIP systems are typically controlled by a central control panel or programmable logic controller (PLC). The control system manages the operation of pumps, valves, and other components, allowing for automated and precise cleaning cycles.

–Control Instruments and valves: Mass flowmeters, temperature sensors, pneumatic valves, frequency converter, pipelines, etc.

1. The economic operating cost of the CIP cleaning system is low, the structure is compact, and the floor space is small. Installation and maintenance are convenient. The CIP cleaning system can effectively clean the production equipment such as tanks, machines and pipes. The entire cleaning process is in a full closed environment, which can avoid the chance of secondary pollution.
2. The CIP system can be divided into one to four routes according to production needs. In particular, the second and above routes can not only clean the same area or two or more areas at the same time but also can clean while producing during the production process. This greatly shortens the CIP cleaning time during production.
3. The CIP system uses a pneumatic diaphragm pump to pump concentrated acid and alkali, which not only improves the equipment intact rate and reduces the maintenance rate of the equipment, but also reduces the operating cost.
4. Especially the fully automatic CIP, which can automatically detect, add liquid, discharge, display and adjust the cleaning liquid. It runs reliably, has a high degree of automation, simple operation and good cleaning effect, so it is more suitable for modern large-scale fluid medicine. Hygienic requirements and production environment requirements for food processing technology.
5. Automatically switch various process parameters, and automatically adjust parameters such as cleaning time, PH, temperature, etc.
6. All operations can be recorded to facilitate GMP certification.
7. The CIP cleaning system has single-tank double-tank and multi-tank for users to choose from. There are a mobile and fixed type.
8. In food and beverage processing plant, all the tanks, pipelines and equipment need to be cleaned daily to keep the whole production line sanitary.
9. The main configuration of the system: automatic Siemens PLC control system and 12-inch color touch screen, British Spirax Sarco steam pressure reducing valve, Korea JK steam trap, German temperature detection and adjustment system, German JUMO or Negee conductivity meter, German IFM flow switch.
10. The whole system can realize automatic control of tank temperature and discharge temperature, automatic control acid and alkali concentration and compensation, automatic alarm of equipment failure to be cleaned, automatic control of liquid level in the tank, automatic switching of CIP process, and self-cleaning of the tank.
