The cleanliness of peanut roasting machine affects the life of the machine

In the food processing industry, the peanut roasting machine can be called “flavor magician”, but this precision equipment is very “delicate”. In daily production, the omission of cleaning and maintenance is often like planting a time bomb, which eats away the life of equipment over time and eventually evolves into a major crisis affecting production.

First, the invisible hidden danger: the chain reaction of oil accumulation.

During the roasting process, the oil released by peanuts will form stubborn oil scale at high temperature. These grease stains are attached to the surface of the heating tube, just like putting a “heat insulation coat” on the heating element, which reduces the heat conduction efficiency by more than 30%. Due to the long-term failure to clean the heating pipes in a food factory, the energy consumption of equipment increased by 22% year-on-year, and the service life of heating pipes was shortened by nearly half. The oil film on the fan blades will break the dynamic balance. An enterprise failed to deal with the abnormal vibration of the fan in time, which eventually led to a motor burning accident, resulting in tens of thousands of direct losses.

Second, fatal wear: mechanical disaster caused by debris.

The peanut crumbs produced by roasting seem insignificant, but there are hidden dangers. When the debris enters the transmission chain, gear box and other precise parts, it will act as “miniature sandpaper”. According to the equipment maintenance data, the transmission parts of the peanut roasting machine without regular cleaning of debris wear 4 times faster than normal. A medium-sized processing factory once broke the chain due to excessive wear, which caused the production line to stop for 12 hours and the direct economic loss exceeded 150,000 yuan. What’s more, the accumulated debris will also become a hotbed of microorganisms, polluting the follow-up products and forming food safety hazards.

Third, the misconception of cleaning: the invisible harm of wrong operation.

Improper operation in the cleaning process is equally fatal. Scraping the equipment with steel wire balls will cause surface scratches, and these microscopic gullies will become “safe havens” for oil hiding, which will accelerate the corrosion process. However, due to the abuse of highly corrosive cleaning agents, an enterprise used industrial degreaser, resulting in honeycomb corrosion of stainless steel liner, and had to replace the core components worth 80 thousand yuan in advance. In addition, if the equipment is not completely dried after cleaning, the metal parts will rust under the action of water vapor, and the maintenance cost of a roaster is as high as 50 thousand yuan because of the short circuit of water inlet in the electric control box.

Fourth, scientific maintenance: the golden rule of prolonging equipment life.

Establishing standardized cleaning process is the key to equipment longevity. It is suggested to adopt a three-level maintenance system of “daily cleaning+weekly maintenance+monthly maintenance”: wipe the surface with neutral cleaner every day, disassemble the parts prone to fouling such as fans every week for deep cleaning, and lubricate and maintain the transmission system every month. Equipped with a special cleaning kit to avoid using damaging cleaning materials. By implementing this maintenance scheme, a food group has extended the average service life of the roaster from 5 years to 8 years, and reduced the average annual maintenance cost by 40%.

The service life of the peanut roasting machine is like fine sand in an hourglass, and every cleaning omission is accelerating. Only by upgrading equipment maintenance to a strategic level and establishing a scientific maintenance system can this “flavor magician” create value continuously and steadily. After all, every careful care of the equipment is a double guarantee for production efficiency and product quality.
