Description
Technical field
The invention belongs to Chinese crude drug manufacture field, relate to a kind of Chinese crude drug physical mildewproof insect-prevention treatment method.
Background technology
The processing in production place of Chinese crude drug is the preliminary working link in Producing medicinal herbs, is also the important step ensureing Chinese crude drug quality, not only affects the quality of Chinese crude drug, also affect its clinical practice and storage.Along with the planting technology further normalization of Chinese crude drug, cultivated area expands, every collecting season, and a large amount of medical material is faced with dry problem, if dry not in time, fresh medical material is very easily mouldy, rotten, drastically influence the output of Chinese crude drug.The Traditional Sun dry method that the place of production is commonly used is large to weather degree of dependence, and rate of drying slowly.At present, the mildew and insect proof of Chinese crude drug usually adopts sulfur, aluminum phosphide fumigation or soaks with sulphite, although said method can realize medical material rapid draing, kill worm's ovum, ensure the color and luster of medical material simultaneously, but above method not only contaminated environment also makes health be on the hazard, also there is impact to the nature and flavor of Chinese crude drug itself, chemical composition and drug effect.And the chemical contamination in pesticide residues and food and medicine production process is deepened the understanding of health hazard along with people, the method for soaking food and medicine with sulfur, aluminum phosphide fumigation and sulphite will be prohibited.
Summary of the invention
The object of the invention is to for prior art Problems existing, provide a kind of rate of drying fast and the Chinese crude drug physical mildewproof insect-prevention treatment method of safety and sanitation nonhazardous.
For this reason, the present invention adopts following technical scheme:
A kind of Chinese crude drug physical mildewproof insect-prevention treatment method, comprises the steps:
(1) will be organized into width through remove impurity, cleaning, dried crude drug is 300-400mm, and thickness is the strip stack medical material of 5-20mm;
(2) add wet process to stack medical material, amount of water is the 5%-40% of medical material weight, and fresh-cut Chinese crude drug does not then need to carry out adding wet process;
(3) sterilization treatment is carried out by the microwave tunnel of the medical material feeding micro-wave drying sterilising apparatus after humidification, sterilisation process is: open micro-wave drying sterilising apparatus power supply, Chinese crude drug is put into the conveyer belt of micro-wave drying sterilising apparatus from the feeding mouth tiling of equipment starting end, control medical material tiling thickness and be no more than 20mm, by conveyer belt transmission, sealed microwave radiation area medical material being sent into continuously micro-wave drying sterilising apparatus stage casing carries out microwave drying sterilization;
(4) medical material that dry sterilization is good is sent from the equipment tail end discharging opening be arranged in the clean operating space of micro-wave drying sterilising apparatus with conveyer belt, collects, enters bag, for subsequent use;
(5) medical material after microwave drying sterilization is carried out determination of moisture, it is qualified that moisture reaches 11-14%, weighed by the tcm and herbal slice reaching moisture requirement, the tcm and herbal slice not reaching moisture requirement continues into micro-wave drying sterilising apparatus drying; Tcm and herbal slice evacuation after weighing is packed laggard luggage case;
(6) Chinese crude drug after above-mentioned vanning put into the dry constant heat storage storage of 5-10 DEG C or sell.
Further, in step (3), the microwave frequency of microwave drying is 2000-3000MHz.
Further, in step (3), described feeding mouth is arranged on micro-wave drying sterilising apparatus normal operations district, and conveyer belt transmission speed is 40-100mm/min.
Further, in step (5), tcm and herbal slice is stacked neatly mutually, and tcm and herbal slice after shaping is carried out evacuation packaging, and vacuum degree maintains more than 0.04MPa, and load carton or wooden case, every case can fill 20-30kg.
The principle of Chinese crude drug microwave drying sterilization of the present invention is as follows:
The principle of microwave drying sterilization relates to two aspects, and its existing heat effect sterilizing, have again non-thermal effect sterilizing, therefore it has double sterilization function.During microwave heating, the protein in bacterial body, nucleic acid compositions equimolecular polarity group, high speed rotating vibration under microwave field, on the one hand heating makes bacterioprotein solidify and dead; Also can make on the other hand protein, nucleic acid denaturation and dead.Utilize pulse modulated microwave energy to carry out bactericidal assay, the object of sterilization can be reached with less temperature rise.This illustrates microwave disinfection just heat sterilization, also has the ability of the lethal antibacterial of non-heating power, Here it is so-called non-thermal effect.Around this principle, the pulsed microwave energy of several times higher than the conventional microwave density of field energy or decades of times can be adopted within the extremely short time, not only reliably can kill antibacterial, also can greatly reduce medicine temperature rise, reduce the energy consumption of equipment.In pharmaceutical production, often use uviol lamp, xeothermic, the method such as steam, Co 60, ozone sterilizes, microwave technology then opens again a kind of ideal style, can at short notice, sterilize to material inside and outside simultaneously.
The main feature of Chinese crude drug microwave drying sterilization of the present invention is as follows:
(1) rate of drying is fast;
(2) uniform drying, good product quality.Because micro-wave drying is from internal batch heat drying, and have autobalance performance, even if so heating object material is complex-shaped, heat drying is also uniform, and scorched outside and underdone inside phenomenon can not occur;
(3) can keep by the original characteristic of dry product, all beneficial to improving the quality of products;
(4) thermal efficiency is high.Because heat is directly from internal batch, therefore the loss of heat around in air is few.Microwave drying and hot-air dry combine, and can obtain satisfied drying effect.
To sum up, compared with prior art, advantage of the present invention and beneficial effect as follows:
(1) the present invention adopts microwave desinsection enzyme denaturing technology, effectively shorten drying time and saved the energy, and product is without sulfur dioxide residue, effectively improve Chinese crude drug product quality;
(2) microwave technology be combined with vacuum packaging and constant temperature storage technique and carry out, method is simple, is easy to industrialization;
(4) microwave technology used in the present invention and vacuum-packed technique and constant temperature storage technique all belong to physical method, meet standards of pharmacopoeia, produce in the course of processing without harmful, noxious substance.
