Embodiment Construction

[0015] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] like Figure 1-Figure 2 Shown, a kind of menthol baking method comprises the following steps:

[0017] S1: Open the mouth of the crystallization barrel containing menthol crystals, place the crystallization barrel on the mobile trolley, push the mobile trolley into the drying room 1 along the track, and close the door of the drying room 1. The mobile trolley includes the trolley body 5. Rotate the moving roller 4 arranged under the trolley body 5 and matched with the guide rail 3, rotate the eccentric turntable 6 arranged above the trolley body 5, and drive the eccentric turntable under the trolley body 5 6 rotating drive motor 7, a fixing device f...

Abstract

The invention provides a menthol baking method. The method comprises S1, opening a barrel mouth of a crystallizing barrel, placing the crystallizing barrel on a moving trolley, pushing the trolley into a baking room and closing a baking room door, S2, carrying first baking through opening a steam valve of the baking room, simultaneously driving an eccentric turntable to rotate through a driving motor so that molten liquid drops and residual oil flow into an oil collecting disc through a barrel nozzle, and when a temperature sensor detects that the temperature of a crystallizing disk is increased to 42 DEG C, controlling the steam valve to close through a PLC control system, and S3, carrying out second baking through detecting the liquid levels of the liquid drops and residual oil through aliquid level sensor, controlling the driving motor to stop through the PLC control system, simultaneously opening the steam valve, when the temperature sensor detects that the temperature of the crystallizing disk is increased to 42.5 DEG C, controlling the steam valve to close through the PLC control system, when a concentration detector detects that the concentration of the molten liquid dropsis the same to the purity of the qualified crystal, keeping the temperature for 2h and opening the baking room door for cooling.

Description

technical field [0001] The invention relates to a method for baking menthol. Background technique [0002] The purpose of the baking process is to send the crystallized menthol to the finished product drying room at a temperature of 42.5-44.5°C, and to bake the menthol whose melting point on the crystal surface is below 42.5°C, because the national standard clearly stipulates that the melting point of menthol is Between 42.5-44.5°C. The most fundamental purpose of baking is to remove impurities to ensure that the crystallized impurities are as low as possible. In addition, the saturated solution obtained by drying contains a considerable concentration of menthol and other impurities, which can be fully dehydrated and mixed with mint crude oil, ice oil, or brain root, etc., and then recrystallized. [0003] In the whole baking process, technical personnel with certain rich experience are needed to control the temperature, concentration and variation range, but there are una...
