Processing method of Flos Lonicerae

The processing of honeysuckle includes rough processing and fine processing (deep processing), which is mainly introduced here.

(1) sulfur fumigation: honeysuckle recovered can be fumigated after removing branches, leaves and impurities. A small amount of flowers can be fumigated with small wooden cabinets, water tanks, steamed rice cages, etc., and those with a large amount of flowers (more than 200 jin) can be fumigated by fumigation pools. The pool can have two to three floors, each with a distance of 40 centimeters, and covered with a bamboo mat, and then spread the honeysuckle on the bamboo mat (be careful not to press the honeysuckle), with two ventilation holes on each floor. Each floor should be covered with sacks or cloth, so that there is no air or less air. After sulfur burning, generally smoked for 12 hours, the smoked honeysuckle is soft and hot, keep the original color, and the unsmoked flowers are hard.

The collection of honeysuckle is in Grain Rain's season, most of which are rainy and cloudy and cannot be dried at once. The fumigated honeysuckle can be stored temporarily for a period of time. The individual practice is to choose a brick pool, wooden bucket or water tank, turnip basket, etc., covered with a clean plastic film, put the freshly smoked honeysuckle in it, and wrap it up to prevent the sulfur from being lost. It can be preserved for a month or so. Turn in the sun when the weather clears up.

(2) drying by slow fire in the roasting room: the pipe type is used in the roasting room to make the temperature in the room uniform. The pipe must be airtight and smoke must not be leaked. Several floors are set up in the room, and the thickness of honeysuckle on each floor is about one inch. When the feeding is finished, there will be a fire. Pay attention to control the indoor temperature, first of all, from low to high, gradually rise, the maximum temperature can not exceed 70 °C. When the honeysuckle is roasted to 70% or 80%, it should be dried.
