Embodiment 1

[0019] The bamboo fiber lunch box of the present embodiment comprises the following steps with the environmental protection leak-proof sealing method:

[0020] The bamboo fiber lunch box includes a box body processed from bamboo and a lid matched with the box body;

[0021] Step 1. Mix and stir the potato starch and water to form a starch emulsion, then add the starch emulsion into the gelatinization tank, and then feed steam into the gelatinization tank to heat the starch emulsion to a temperature of 60°C, and keep it warm while stirring 2.5h to obtain starch slurry; the mass content of potato starch in the starch emulsion is 40%;

[0022] Step 2, apply the starch slurry obtained in step 1 on the surrounding edges of the inner surface of the lid, the thickness of the coated starch slurry is 0.15mm, and then the lid is processed under the condition of 165 ° C. The drying process of 2min forms the pregelatinized starch film on the inner surface of lid then;

[0023] Step 3. A...

Abstract

The invention discloses an environment-friendly leakproof sealing method for a bamboo fiber meal box, which comprises the following steps: mixing and stirring potato starch with water, and gelatinizing the mixture to obtain starch slurry; coating the starch slurry on the inner surface of the box cover and drying the slurry to obtain a pre-gelatinized starch film; spraying a water film to the pre-gelatinized starch film, and buckling the box cover on the box body filled with the food after the pre-gelatinized starch film is completely dissolved, so that the dissolved pre-gelatinized starch filmis in contact with the upper edge of the box body; and sealing the buckled bamboo fiber meal box after the pre-gelatinized starch film is dried. According to the invention, the adhesive property of gelatinized potato starch is utilized; the box cover and the box body are connected in a sealed mode, the problem that food liquid overflows and leaks in the lunch box transportation process is solved,the problem that disposable lunch box waste seriously pollutes the environment is solved, the leakproof requirement of the bamboo fiber lunch box in actual use is met, and large-scale application andpopularization of the bamboo fiber lunch box are facilitated.

Description

technical field [0001] The invention belongs to the technical field of meal sealing, and in particular relates to an environmentally friendly leak-proof sealing method for a bamboo fiber lunch box. Background technique [0002] At present, disposable plastic lunch boxes are still commonly used in the catering industry, causing more pollution. A small number of bamboo fiber lunch boxes prepared by steam explosion technology have good environmental protection and economic benefits and can be used as substitute materials for plastic lunch boxes. However, due to the fact that a reasonable and environmentally friendly anti-spill sealing measure has not been developed yet, the plastic sealing method is still used for sealing. Although this plastic sealing method can solve the problem of sealing, when the lunch box is opened for dinner, the plastic sealing film material will be broken. Produce plastic waste, cause environmental protection problem, for some areas that prohibit plas...
