10 tips to maintain brewing equipment

1. Do not use cl-detergent or disinfectant. It should be obvious, but we’ll mention it anyways!
2. If you’re not going to use your equipment for a while, make sure you clean the equipment thoroughly. After the water flow is cleared, close the valves. Also, clean the equipment thoroughly before reusing it after a long period of time.
3. The heat exchanger should be disassembled and cleaned after long-term operation or if hasn’t been used for a long time. No metal brush is allowed during cleaning, no bending, twisting, trampling and extrusion of heat exchanger plate are allowed. And the aged sealing gasket should be replaced in time.
4. Check the electrical motor, pump connection and grounding regularly to ensure correct connection. Check the oil level of reduction motor and hydraulic device. Add lubricant regularly according to the instruction. Check the fastening of stirring and tillage fittings regularly. All pumps used shall not be idled or reversed, and the pump seal shall be replaced in time if leakage is found.
5. Check regularly whether there are foreign matters and impurities in the hopper of the grinder, check whether the fasteners of the grinder are loose, the tightness of the driving belt of the grinder and the reliability of safety protection devices. Clean the grinder roll regularly.
6. Check the pressure gauges and safety valve of steam heating equipment regularly, and ensure the steam trap is free; Do not start heating until the specified level is reached. Warning signs shall be hung on the top of steam, wheat juice and other high temperature pipelines and saccharification equipment during operation to prevent burns.
7. When filtering, do not extract wort in high flow and damage the sieve plate! When the equipment is not used, the weight shall not be placed on the screen plate to avoid deformation of the screen plate. Keep all mechanical parts running smoothly during operation.
8. Check whether the plate heat exchanger has leakage, leakage and fluid flow at any time, and repair immediately if any.
9. Pay attention to the concentration of alkali water in the alkali water tank at any given time. If it is found that the concentration of alkali water is too low or too turbid, it should be replaced in time for washing.
10. Check all pipe valves at any time. If leakage is found, repair or replace it immediately.

7 Tips to Maintenance beer fermentation tank

Beer fermentation tanks are widely used in beverage, chemical, food, dairy, seasoning, brewing, pharmaceutical and other industries, and play a role in fermentation. The tank is mainly used to cultivate and ferment various bacterial cells, and the sealing is better (to avoid bacterial contamination), so how to maintain it?

1. If the air inlet pipe and the water outlet pipe joint leaks, when tightening the joint does not solve the problem, the filler should be added or replaced.
2 The pressure gauge and safety valve should be checked regularly, and if there is any fault, it should be replaced or repaired in time.
3. When cleaning the fermenter, please use a soft brush to scrub, do not scratch with a hard tool to avoid damage to the surface of the fermenter.
4. The supporting instrument should be calibrated once a year to ensure normal use.
5. Electrical equipment, instruments, sensors and other electrical equipment are strictly prohibited from directly touching water and steam to avoid moisture.
6. When the equipment is out of use, it should be cleaned in time to drain the remaining water in the fermentation tank and each pipeline; loosen the fermentation tank cover and hand hole screws to avoid deformation of the sealing ring.
7. If the fermentation tank is not used temporarily, it is necessary to empty the fermentation tank and drain the remaining water in the tank and in each pipeline.

The beer fermentation tank can withstand steam sterilization, has certain operation flexibility, minimizes internal accessories (avoid dead ends), has strong material and energy transfer performance, and can be adjusted to facilitate cleaning and reduce pollution, suitable for the production of various products and reduce energy consumption.

Frequently Asked Questions (FAQ)

• Q1: How often should I deep-clean my brewing equipment?
  A1: Perform a full CIP (clean-in-place) and inspection every 20–40 brews or quarterly—whichever comes first. Heat exchangers, pumps, and fermenter fittings may require monthly checks in high-throughput breweries.
• Q2: What cleaners are safest for stainless steel brewing equipment?
  A2: Use non-chlorinated alkaline cleaners (e.g., caustic or percarbonate) for soils, followed by acid rinses (phosphoric/nitric blends) to remove beer stone. Avoid chlorine-based agents to prevent pitting and chloride stress corrosion cracking.
• Q3: How can I extend the life of my plate heat exchanger?
  A3: Track differential pressure and flow rates, disassemble for manual inspection at least twice per year, replace aged gaskets proactively, and never use metal brushes. Keep spare gasket kits on hand.
• Q4: What’s the best practice for pump maintenance in a brewery?
  A4: Verify grounding, alignment, lubrication schedules, and mechanical seal integrity weekly. Never run pumps dry or reversed; replace seals at the first sign of leakage.
• Q5: How do I prevent contamination in fermentation tanks?
  A5: Maintain validated CIP cycles, verify spray-ball coverage, calibrate sensors annually, and ensure all seals, PRVs, and manway gaskets are intact. Use steam or chemical sterilization as appropriate to your tank’s rating.

2025 Industry Trends for Brewing Equipment Maintenance

• Rising chloride limits: Breweries are tightening incoming water chloride below 50 ppm to reduce stainless pitting incidents in hot-side equipment.
• Predictive maintenance: Affordable inline sensors and cloud analytics are enabling condition-based servicing of pumps, heat exchangers, and CIP skids.
• Water and chemical reduction: Breweries target >25% cuts in CIP water and chemical use via recovery loops and low-conductivity endpoints.
• Energy-efficient CIP: Heat recovery from wort cooling and insulated CIP tanks are becoming standard to meet Scope 2 targets.
• Regulatory focus: OSHA/EU directives emphasize lockout/tagout, steam safety valves, and pressure vessel inspection logs.
