Shutdowns and Long Idle Periods: How to Store and Restart a Machine

During the off-season, for seasonal products, or when a plant relocates, a machine may sit idle for weeks or months. Before shutdown, clean and dry it thoroughly, protect it from rust, release tension, and disconnect the power. During storage, protect it from moisture and pests. Before restarting, inspect it fully, clean and sanitize, lubricate, run it empty, and then do a small trial run.

Relocating and Reinstalling Machinery

When a plant moves or a line is reconfigured, machines have to be moved. Small tabletop machines can be moved in-house, but disassembling, lifting, anchoring, wiring, and calibrating large equipment is best handled by the equipment maker or a professional team. After the move, always re-level, inspect, and test-run, and recalibrate if necessary.

Operator Hygiene Requirements: Hands, Clothing, and Health

Operators' hands, clothing, and hair can also carry contamination into products. Annex 2 of Taiwan's Regulations on Good Hygiene Practice for Food requires health checks before hiring and every year, work clothes, caps, shoes, and masks, no long nails or jewelry, and no contact with food while hand injuries and similar conditions persist.

Production Records and Quality Checks: How to Do Weight and Appearance Checks

The advantage of machine production is consistency, but consistency has to be proven by inspection. How many pieces to weigh per batch, what to record, and how to set acceptance ranges are not fixed by the regulations, but they do require records of process and quality control and confirmation that every batch of finished product meets quality assurance requirements. This article provides a practical approach you can use right away.

Product Changeover Steps and Allergen Management

Making pork dumplings in the morning and vegetarian dumplings in the afternoon on the same machine, or switching from red bean paste to sesame filling, is a changeover. A changeover may mean swapping nozzles, molds, or settings, or it may require a full teardown and wash. The time depends on the model and how different the products are; when allergens or vegetarian products are involved, cleaning must be stricter than daily cleaning.

Act Governing Food Safety and Sanitation: Basic Rules for Food Factories and Shops

If you make dumplings or buns to sell, you are a "food business" under Taiwan's Act Governing Food Safety and Sanitation. This article summarizes the Act's basic obligations for businesses (hygiene practice, registration, document retention, labeling) and the range of fines and criminal penalties in Articles 44 to 49, citing the current article numbers.

What Is HACCP (Food Safety Control System), and Who Must Implement It?

HACCP is a management system that uses hazard analysis to identify critical control points and monitors each one. This article summarizes the elements of Taiwan's Regulations on Food Safety Control System and the sectors and scales currently required by TFDA notices to implement it, including the rules for seafood, meat, dairy, and canned foods amended on March 17, 2026.

Food Business Registration (FADENBOOK): Who Must Register and What to Prepare

This article summarizes the items each industry category must register under the Regulations Governing Registration of Food Businesses (amended January 5, 2026), the deadlines for changes and annual confirmation, and how food utensil manufacturers can check whether they fall within the notice.

Sanitation Standard for Food Utensils, Containers and Packaging: Are Machine Contact Parts "Food Utensils"?

Taiwan's Food Safety Act classifies machinery in direct contact with food as "food utensils," so contact surfaces must meet the Sanitation Standard for Food Utensils, Containers and Packaging. This article covers the legal definition of utensils, the general provisions and migration tests of the current standard (January 11, 2023), and the material documentation buyers and sellers commonly keep on hand.

Materials in Contact With Food: Stainless Steel, Food-Grade Plastics, Rubber

Food contact surfaces on food machinery must resist corrosion, not leach, and be easy to clean. Based on Taiwan's Sanitation Standard for Food Utensils, Containers and Packaging, the factory establishment standards, and EU Regulation 1935/2004, this article covers key points for choosing stainless steel, aluminum, plastic, and rubber or silicone parts, and common questions on the plant floor.
