Embodiment 1

[0032] Production of fully degradable tableware and bowl products. Carry out batching (calculate with weight %) in following proportion:

[0033] 1) Potato starch 40; 2) Light calcium carbonate 6; 3) Edible talcum powder 40; 4) Straw fiber 6; 5) Edible gypsum 2; 6) Methylcellulose 4; 7) Monoglycerin 1; 8) Food grade guar gum1.

[0034] After the batching is completed, put it into the mixer, and add water in a ratio of 100:35, the water temperature is 100°C, and stir for 6-7 minutes; after stirring evenly, press the bowl embryo, and perform high-temperature heat setting, the setting temperature is 180-200 ℃, the time is 35-40 seconds; followed by cooling for 12 hours to make the product shrink naturally; after that, enter the coating process, the temperature is controlled at 80-90 ℃, the time is 7-8 minutes, the coating material is waterproof, The amount of oil-proof edible spray coating liquid is sprayed according to the dose of 3-5g for each product; finally, it is steriliz...

Embodiment 2

[0036] Production of fully biodegradable tableware cups. Batching is carried out according to the following raw material proportioning (in % by weight). Raw materials and proportioning are:

[0037] 1) sweet potato starch 38; 2) light calcium carbonate 9; 3) edible talcum powder 30; 4) straw fiber 9; 5) edible gypsum 4; 6) methylcellulose 6; 7) monoglycerin 2; 8) edible Grade Guar Gum 2.

[0038] After the batching is completed, put it into the mixer, and add 40% water, stir at the water temperature of 100 ° C, after 6 to 7 minutes, after stirring evenly, it can be pressed into shape, and then, at the temperature of 180 ~ 200 ° C, after 45 Seconds for high-temperature setting, and then after 10 hours of cooling back to the original; then transfer to the coating process, each product is spray-coated with waterproof and oil-proof spray liquid, and each cup is coated with 4 grams ; After ultraviolet sterilization and disinfection, packaging and storage are carried out. The en...

Embodiment 3

[0040] Production of fully biodegradable cutlery trays. In weight percent, carry out batching, raw material proportioning:

[0041] Tapioca starch 47.5; light calcium carbonate 5.0; edible talc powder 33.0; corn orange stalk fiber 6.0;

[0042] Edible gypsum 2.0; methylcellulose 4.0; monoglycerin 1.0; edible guar gum 1.5.

[0043] After batching according to the above formula, put it into the mixer, then add 100:30 clear water, raise the temperature to 100°C, and stir for 6-7 minutes; after stirring evenly, press the disc embryo, and perform high-temperature heat setting, and the setting temperature is controlled at 190°C , the time is 40 seconds; then 12 hours of natural cooling back to the original; after that, transfer to the coating process, the temperature is controlled at 85 ° C, the time is 8 minutes, the coating is edible spray liquid, and the amount is sprayed according to the surface of each plate The amount of 5g controls the feeding speed; then enters the sterili...
