Three-chamber-drying-based cocoon drying machine

Abstract

The invention relates to a three-chamber-drying-based cocoon drying machine comprising a cocoon drying chamber, a feeding belt, a bearing box, and a plurality of conveying belts. The cocoon drying chamber is divided into a first-stage cocoon drying chamber, a second-stage cocoon drying chamber, and a third-stage cocoon drying chamber by a first-stage chamber separation board, and a second-stage chamber separation board; and the first-stage cocoon drying chamber, the second-stage cocoon drying chamber, and the third-stage cocoon drying chamber are connected with a first-stage hot blast heater, a second-stage hot blast heater, and a third-stage hot blast heater respectively by respective blast pipes. Hot air board boxes are respectively arranged in the first-stage cocoon drying chamber, the second-stage cocoon drying chamber, and the third-stage cocoon drying chamber; and air-out nozzles are arranged at the sides, facing the conveying belts, of the hot air board boxes. According to the invention, the internal environments of the first-stage cocoon drying chamber, the second-stage cocoon drying chamber, and the third-stage cocoon drying chamber do not influence each other much and the temperature range can be controlled easily. Silkworm cocoons can be dried at three different temperature environments and drying of the silkworm cocoons and reelability of silks can be realized ideally.

Description

technical field [0001] The invention relates to a three-chamber drying cocoon drying machine, which belongs to the field of machinery. Background technique [0002] The silkworm cocoon includes the cocoon layer and the silkworm chrysalis in the cocoon layer. The cocoon layer is an important raw material for the silk cutting industry in the silk industry. There are two purposes for drying the cocoon. One is to evaporate the water in the cocoon to facilitate storage. The other is to While removing the moisture of the cocoon layer and silkworm chrysalis in the silkworm cocoon, it is also necessary to protect the good release of the cocoon layer, properly denature the sericin, and reasonably increase the resistance of the cocoon layer to boiled silkworms, so as to meet the requirements of the silk-killing process. Therefore, the changes in temperature, humidity and wind speed of the silkworm drying machine during the drying process of silkworm cocoons and the relative relationsh...
