Embodiment 1

[0014] Put 30 liters of clear water in a 60 liter stainless steel bucket, add 1000 grams of glucomannan and 10 grams of food grade calcium hydroxide, stir and mix evenly, divide them into molds, and heat in a steamer at 115 ° C for 1 hour. Naturally cool to room temperature, put into the freezer for 4 days at -10°C, leave the freezer to thaw naturally, punch holes with fine needles after demoulding, centrifugal dehydration, dry, and seal the package. The glucomannan sponge has a small pore size and a short production cycle.

Embodiment 2

[0016] Put 60 liters of clean water in a 60 liter stainless steel bucket, add 1000 grams of glucomannan and 50 grams of food grade calcium hydroxide, stir and mix evenly, put them into molds, and heat in a steamer at 100°C for 4 hours. Naturally cool to room temperature, put into the freezer for 60 days at -1°C, leave the freezer to thaw naturally, punch holes with fine needles after demoulding, centrifugal dehydration, dry, and seal the package. The glucomannan sponge has a large pore size and a long production cycle.

Embodiment 3

[0018] Put 50 liters of clear water in a 60 liter stainless steel bucket, add 1000 grams of glucomannan and 40 grams of food grade calcium hydroxide, stir and mix evenly, divide them into molds, and heat in a steamer at 102°C for 4 hours. Naturally cool to room temperature, put into the freezer for 30 days at -2°C, leave the freezer to thaw naturally, punch holes with fine needles after demoulding, centrifugal dehydration, dry, and seal the package. The glucomannan sponge has a larger pore size and a longer production cycle.

Abstract

The invention relates to an environment-friendly preparation method for a glucomannan sponge. The environment-friendly preparation method aims to overcome the defects of generation of a great deal of alkaline sewage and decolored sewage and severe environmental pollution in the prior technology for producing a konjak sponge for bathing, and provide the environment-friendly preparation method for the glucomannan sponge for bathing, wherein the alkaline sewage and the decolored sewage can not be generated in the manufacturing technique. The environment-friendly preparation method for the glucomannan sponge comprises the following steps: glucomannan is adopted as a raw material and calcium hydroxide is adopted as a gelation-stimulant, and the glucomannan and the calcium hydroxide are weighed in proportion, added into water and uniformly mixed; a mixture is filled into a die which is then placed into a steaming tool for solidification; after the solidification is over, the mixture of the glucomannan and the calcium hydroxide forms monolithic gel; the monolithic gel is frozen, naturally unfrozen after freezing is over, and forms a glucomannan sponge semiproduct after unfreezing; and the semiproduct is subjected to demoulding, dehydration and drying to obtain the finished product of the glucomannan sponge for bathing.

Description

technical field [0001] The invention belongs to the technical field of bath sponge preparation, in particular to an environmentally friendly preparation method of glucomannan sponge. Background technique [0002] Traditional sponges for bathing mostly adopt chemical raw materials to be made by chemical methods. The disadvantage of this sponge is that the manufacturing process is complicated and the environmental pollution is more serious. Because its products are made of chemical raw materials, they have certain pollution to the human body during use, especially when they directly act on human skin. In order to overcome the shortcomings of traditional bath sponges, people have developed konjac sponges. Although the bath sponges made of konjac sponges are not corrosive to human skin, in the production process of konjac sponges, due to the influence of konjac powder Influenced by impurity factors such as polyphenols and organic acids in raw materials, a large amount of alkal...
