Abstract
The invention discloses a green preparation system and method of a moisture-resistant food deoxidizer, which belong to the technical field of food preservation and sequentially comprise a deoxidizing carrier forming device, a deoxidizing carrier impregnating device, a deoxidizing carrier adhering device, a dicing device and a packaging device, wherein the deoxidizing carrier forming device sequentially comprises an opener, a net forming machine and a needling machine, and the deoxidizing carrier adhering device is an ultrasonic composite device capable of realizing ultrasonic hot-pressing welding of three sheets. The beneficial effects of the invention are as follows: through ultrasonic hot-pressing welding, the composite cost can be reduced, and the space structures inside the first base cloth layer and the second base cloth layer can be kept from being damaged to the greatest extent.
Description
Technical Field
The invention relates to the technical field of food preservation, in particular to a green preparation system and method of a moisture-resistant food deoxidizer.
Background
Spoilage of foods is the most prominent of the quality and safety problems of foods, and brings about a huge economic loss worldwide every year. The key factor causing food spoilage is the growth and metabolism of microorganisms, and the essential factor is that the nutrients such as protein, carbohydrate and fat in the food are decomposed by degrading enzymes secreted by the microorganisms, for example, protein decomposition products include substances such as amines, hydrogen sulfide, mercaptan, indole and skatole which are aversive after being smelled; fatty rancidity produces aldehydes, ketones, etc., and further breaks down to develop a particular rancidity taste. In addition, tissue ulceration, mucus filth and the like of the appearance of the food seriously affect the sensory and hygienic quality of the food, and reduce or lose the use value. The food spoilage not only reduces the nutritive value of the food and causes people to feel aversion, but also can generate various toxic and harmful substances to cause people to suffer acute poisoning or to suffer chronic poisoning, and in order to achieve the purposes of preserving and preserving the food and prolonging the shelf life and the shelf life of the food, various preservation technologies such as refrigeration, irradiation and the like are adopted, but more convenient and economic technologies are a method for preserving the food by adopting deoxidizing agents or preservation cards, for example, chinese patent CN103653185A discloses a moisture-proof deoxidizing agent for the food, which consists of 90-110 parts of iron powder, 5-15 parts of calcium chloride, 5-15 parts of active carbon and 20-40 parts of auxiliary materials; wherein the auxiliary materials are attapulgite and montmorillonite with a mass ratio of 4-6:4-6. Although the moisture-resistant deoxidizer can maintain deoxidizing performance under high humidity condition and is not easy to turn back water, when the packaging bag of the deoxidizer breaks, food is easy to pollute and can not be eaten, and the deoxidizer is hard particles, so that the deoxidizer is easy to collide with food in the transportation process to damage the appearance of the food.
As another example, chinese patent CN107215044a discloses a fresh-keeping card for alcohol flake food and a manufacturing method thereof, comprising a card body made into flake, wherein the card body comprises a first film layer, a substrate layer and a second film layer, the substrate layer is made of a cloth-based material with alcohol, the first film layer is fixedly connected to the bottom surface of the substrate layer by an adhesive, and the second film layer is fixedly connected to the top surface of the substrate layer by an adhesive. Although the anti-mildew agent has good anti-mildew effect, cannot pollute food, can effectively avoid damage to the appearance of the food caused by collision with the food in the transportation process, and has the problems of reduced fresh-keeping effect under the humidity condition and the like.
Disclosure of Invention
The invention discloses a green preparation system and method of a moisture-resistant food deoxidizer, aiming at the problems that the fresh-keeping effect cannot be well processed at the same time in the prior art and foods are easy to be polluted by fresh-keeping materials, and the like.
Through ultrasonic hot-pressing welding, the composite cost can be reduced, and the space structures inside the first base cloth layer and the second base cloth layer can be kept from being damaged to the greatest extent.
Preferably, the deoxidizing carrier adhering device comprises a feeding roller set, a press-attaching workbench and a pressing component, wherein the feeding roller set comprises a first feeding roller set for conveying an upper second base cloth layer, a second feeding roller set for conveying a middle first base cloth layer and a third feeding roller set for conveying a lower second base cloth layer, the feeding roller set is arranged at the inlet position of the press-attaching workbench, and the pressing component is positioned right above the press-attaching workbench.
