How to maintain the lubrication system and upkeep of food extruder

A food puffing machine is a device used to process puffed food. Its main working principle is converting mechanical energy into thermal energy, using the heat generated by the machine's rotation to cook and extrude the food. The most notable characteristic of puffed food is its increased volume. After using the food puffing machine for a period of time, it is necessary to inspect it to check whether its components have any issues. Below, the editor will provide a detailed introduction to the inspection of the lubrication system of the food puffing machine.

1. Before starting the machine, carefully check whether each lubrication system has been filled with lubricating oil. Typically, the main gearbox is pre-lubricated at the factory, but after the user completes equipment debugging, the lubricating oil should be replaced with one suitable for the local climate conditions. It is recommended to choose barrel oil from reputable manufacturers.

2. Oil change should be carried out when the engine is hot, meaning that the oil should be drained while the oil temperature has not completely cooled down after the equipment has finished running. After draining the oil, open the gearbox top cover and manually clean residual sludge and other impurities inside the gearbox. At the same time, replace the filter element of the gearbox oil inlet filter.

3. Pour an appropriate amount of diesel into the gearbox to repeatedly clean it, combined with manual cleaning of residual impurities at the bottom of the gearbox. Manually rotate the input shaft and repeat the cleaning process two to three times. After cleaning, add an appropriate amount of lubricating oil, ensuring the oil level is not lower than the center red dot of the oil window.

During operation, the oil level must be checked every shift, and any deficiency should be replenished promptly. Check whether the circulating oil cooling system operates reliably, ensuring that the lubricating oil is replaced every 500–1000 hours of equipment use, or every one to two months depending on usage frequency.

So how should snack food equipment be maintained and serviced? Below, the editor will introduce this to everyone.

1. Maintenance and repair of snack food equipment must be carried out after cutting off the power supply.

2. After each use of the snack food equipment, it should be thoroughly cleaned to ensure food hygiene. During cleaning, do not use sharp tools to scrape the two rollers, nor use a water spray hose for cleaning.

3. Lubricate the gears once per shift from the oil filling point, using gear oil, 20# engine oil, or edible oil. Each application should be a few dozen drops. Replace the lubricating grease in the turbine, worm gear, and bearings every six months, using calcium-based grease.

4. Check the tension and wear of the ordinary V-belt, and adjust or replace it in a timely manner.

5. When the snack food equipment is not in use for an extended period, apply a small amount of edible oil to the surface of the two rollers to prevent rust.
