The invention discloses a method for producing hu chili seasoning powder, which comprises the following process: 1. raw material selecting process; 2. raw material processing process; 3. microwave baking processing; and 4. grinding and packaging process. Dried chilies are taken as raw material with the water content of 12-20%. Impurities are picked and cleaned up, pedicles are removed, so that the dried chilies with seed can be obtained. After the raw material of dried chilies is prepared, the dried chilies are firstly added into a hopper of a microwave drying sterilization machine at the uniform velocity so as to be evenly spread out on a conveyor belt, the thickness of feed layer is controlled to be within the range of 2-4cm, the microwave power is then adjusted to be 6-7kW, the running speed of equipment is 0.5-1m/min, the microwave processing time is controlled to be within the range of 3-5min, the preliminary stage temperature of a heating cavity is 70 DEG C, and the final stage temperature thereof is 100 DEG C. The granules ground by a clean multi-functional grinder are 2-5mm, and are packed by composite film bag vacuum sealed package, hard plastic bottles or glass bottles. The method greatly improves the production efficiency and enhances the production level and the product quality.
