Product Description

The tank body of the craft beer equipment cleaning system produced by Shandong Zunhuang is welded use high-quality 304 stainless steel. The system has a compact structure and is easy to maintain. It can effectively clean the tanks, pipelines and other production equipment in place. The entire cleaning process is carried out in a closed manner. The chance of secondary pollution is greatly reduced, and the entire process is simple to operate. Time saving, high efficiency, power saving, water saving, etc.

The CIP cleaning system of micro brewery can be equipped with different cleaning systems according to the capacity of the equipment. The cleaning system is mainly composed of: alkali tank, acid tank, aseptic water tank, disinfection tank, CIP cleaning pump and other related equipment.

According to the capacity of the production equipment, the cleaning system of the craft brewery has specially developed a mobile cleaning cart suitable for small brewery. Its characteristics are flexible, simple, environmentally friendly, and thorough cleaning and disinfection.

Cleaning In Place (CIP)

Breweries generally use cleaning in place method to clean and sterilize the production system, the process of equipment cleaning and disinfecting in a closed environment without dismantling equipment parts or pipes.

The application of this technology greatly improves the efficiency of cleaning and sterilization.

CIP system design points

The volume of the CIP storage tank should at least meet the 10-minute working flow (volume meter) requirement of the cleaning pump;

If the CIP system needs a return pump to reach the return circulation, the capacity of the return pump should be 20-30% higher than the output pump to avoid CIP liquid accumulating in the system;

The storage tank itself should have a cleaning device and a sewage discharge device;

The storage tank should equip with overflow ports and exhaust holes, and the exhaust holes should be concentrated to the outdoors;

1-Alkali recovery tank; 2-Acid cleaning liquid collection tank; 3-Bactericide collection tank; 4-Recovery water tank; 5-Alkali tank heater; 6-Bactericide cooling; 7-Concentrated alkali storage tank; 8-Acid storage tank; 9-Fungicide storage tank;

The necessary of cleaning

The necessary of cleaning

During the production process, the metal surface in contact with the wort will deposit some dirt due to various reasons. Dirt particles mainly include protein, grease, fat particles, dry yeast, hop resin, beer stone and minerals, etc., which are attached and deposited on the inner surface of equipment and pipes, making them rough and difficult to clean, and providing shelter for microorganisms. At the same time, it weakens the effect of fungicides.

The main purpose of equipment cleaning

Try to wash away the dirt film formed by protein and carbohydrates and deposited minerals.

Since the bactericide can only kill the bacteria on the surface of the dirt, and the living bacteria inside will be exposed later, causing re-contamination, so the existing microbial colonies must be removed when cleaning.

Basic requirements for the cleaning process

The system to be cleaned must be closed.

The cleaning fluid must be in direct contact with the dirt, and the concentration, temperature and time of the cleaning fluid must meet the process requirements, and the mechanical action must all act on the cleaned part.

The cleaned dirt must be discharged from the equipment in a flowing manner, that is, the attachment must be dissolved and removed to prevent the dirt from re-depositing.

The cleaned dirt must be completely discharged from the cleaned system (filtered or separated).

The cleaning agents themselves are harmful to the product, and they must all be discharged from the system being cleaned. As the concentration of acid and lye is diluted during the cleaning process, the concentration needs to be adjusted and tested regularly.

Main factors affecting cleaning

The nature of the dirt (hardness, adhesion, etc.);

Surface roughness of equipment;

Mechanical force (scouring strength);

Types and concentrations of cleaning agents and biocides;

Action temperature;

Action time, etc.

Main factors affecting cleaning time

Dirt;

Type, quality and efficacy of cleaning agent;

The concentration of the active component;

Cleaning temperature;

Mechanical action.

Precautions for cleaning conical tank

A hole should be left at the bottom of the washer so that no residual liquid is left in the washer;

When a rotary jet cleaner is used, it should be able to automatically monitor the rotation and perform regular manual inspections;

The parts higher than the washer should be cleaned reliably by adjusting the nozzle of the washer;

Before cleaning, use air to exhaust the CO2 in the tank, which can prevent the Alkali from absorbing CO2 during cleaning and forming a vacuum in the tank to cause damage to the tank;

For large capacity tanks, the temperature of the cleaning solution should not over 45°C, otherwise the formed vacuum will damage the tank;

The flow rate of the cleaning fluid recovery pump should be higher than that of the cleaning pump (about 25%) otherwise the tank will be "submerged";

After the fermenter is used 3 times, a 1% nitric acid pickling process can be added after alkaline washing to prevent beer stone scale.
