Use and Maintenance of Common Pastry-Making Equipment

I. Oven Usage and Maintenance

1. Oven Usage

Baking is a highly technical process requiring operators to thoroughly understand the characteristics and performance of the oven being used.

(1) Before first use, carefully read the instruction manual to prevent accidents caused by improper operation.

(2) Preheat the oven before baking products. Only begin baking once the temperature reaches the required process specification. Preheating also saves time—do not wait until products are formed to turn on the oven.

(3) Select baking times appropriately based on product process requirements.

(4) Ovens have their own characteristics. Even with identical temperature settings, actual temperatures may vary between different ovens. Therefore, monitor the product's appearance during baking and adjust the temperature promptly.

(5) Turn off the oven immediately after use. Clean any residue from the oven cavity once it has cooled down.

2. Oven Maintenance

Proper oven maintenance ensures normal operation, extends the oven's service life, and is crucial for maintaining product quality.

(1) Keep the oven clean, but avoid using water during cleaning to prevent moisture damage and electrical leakage.

(2) Maintain oven dryness; do not place damp utensils directly inside.

(3) For long-term storage, wipe the oven interior and exterior clean, cover with a plastic cover, and store in a dry, well-ventilated area.

II. Gas Stove Usage and Maintenance

1. Gas Stove Usage

(1) Before use, always confirm the stove knob is off before opening the gas supply valve.

(2) Follow the principle of “ignite first, then supply gas” when operating gas appliances to prevent accidents.

2. Gas Stove Maintenance

(1) Keep the stove clean and ensure burner ports remain unobstructed.

(2) Prolonged use may cause gas hoses to age or rupture, creating safety hazards. Replace aging inlet hoses promptly.

(3) Inspect all stove components for signs of aging or rust to eliminate potential accidents.

III. Mixer Usage and Maintenance

1. Mixer Operation

(1) Before using the mixer, understand its performance, operating principles, and procedures, and strictly follow the operating sequence.

(2) Position the mixing drum on a stable surface to prevent malfunctions during operation.

(3) Do not overload the mixer. Avoid accumulating excessive materials in a single batch and prevent prolonged continuous operation.

(4) Before operation, inspect all components for integrity and confirm proper condition before starting.

(5) Do not forcibly adjust the speed control handle during operation. Shut down the mixer first before changing speeds to prevent damage to the speed control mechanism and transmission components.

(6) Immediately stop the machine upon hearing abnormal noises during operation. Resume only after troubleshooting and resolving the issue.

(7) Do not place foreign objects on the equipment to prevent mechanical debris from falling into and damaging the machinery.

2. Mixer Maintenance

(1) For gearbox-equipped units, promptly replenish lubricating oil to maintain adequate oil levels, reducing friction and preventing gear wear.

(2) Regularly inspect and maintain the equipment's main components, wear parts, and motor.

(3) Keep the mixer clean at all times. Wipe the exterior with lukewarm, mildly alkaline water. Always disconnect the power supply before cleaning to prevent accidents.

IV. Refrigerator Use and Maintenance

1. Refrigerator Use

(1) Position the refrigerator in a well-ventilated area away from heat sources and direct sunlight. Leave at least 10–15 cm of clearance around all sides for proper airflow and heat dissipation.

(2) Food must be neatly arranged and stored according to guidelines. Avoid overfilling the refrigerator. Conduct regular checks and leave gaps between items to maintain airflow.

(3) Separate raw and cooked foods. Do not place hot food directly into the refrigerator.

(4) Minimize opening the refrigerator door to reduce cold air loss.

2. Refrigerator Maintenance

(1) Regularly defrost the refrigerator. Before defrosting, disconnect the power supply and remove all stored food to allow frost to melt naturally. Avoid waiting until frost builds up heavily and attempting to scrape it off with a metal tool, as this can easily damage the appliance.

(2) Avoid frequently disconnecting power while the refrigerator is running, as this causes the compressor to operate under excessive load, shortening the appliance's lifespan.

(3) When storing the refrigerator long-term, thoroughly clean both interior and exterior surfaces, allow them to air dry completely, leave the door slightly ajar, cover with a plastic sheet, and place in a well-ventilated, dry location.
