Embodiment 1

[0024] Embodiment 1, a kind of method that prepares edible biochar bag with kelp, comprises:

[0025] (1) Kelp removal: take the qualified raw material kelp, remove the gravel, and soak it in deionized water for 24 hours;

[0026] (2) Drying and crushing process: first let it dry naturally, and then place it in a blast drying oven at 40°C for overnight drying (drying time is about 12 hours), crush and sieve, put it into a self-sealing tape and place it Store in a dry box for later use;

[0027] (3) Carbonization process: Nitrogen gas is first introduced into the tube furnace to remove the air in the device, then a certain amount of kelp powder is weighed and placed in the tube furnace, and the temperature is raised to 400°C for carbonization, and the carbonization time is maintained for 2 hours;

[0028] (4) Water vapor activation process: Water vapor is introduced from the upper port of the tube furnace to fully activate the biochar (activation time is about 2 hours), and th...

Embodiment 2

[0033] Embodiment 2, a method of preparing edible biochar bags with kelp, comprising:

[0034] (1) Kelp removal: take the qualified raw material kelp, remove the gravel, and soak it in deionized water for 24 hours.

[0035] (2) Drying and crushing process: first let it dry naturally, and then place it in a blast drying oven at 40°C for overnight drying (drying time is about 12 hours), crush and sieve, put it into a self-sealing tape and place it Store in a dry box for later use.

[0036] (3) Activation treatment process: soak the kelp powder with an appropriate amount of chemical active agent for about 2 hours.

[0037] (4) Carbonization process: Nitrogen gas is introduced from the upper port of the tube furnace to remove the air in the device, and the lower port is connected to the gas absorption device. Finally, weigh a certain amount of activated kelp powder and place it in a tube furnace, heat up to a certain temperature (the temperature depends on the activator) for car...

Abstract

A method for producing bagged edible biochar from kelp comprises the following steps: 1, selecting high-quality kelp having good growth vigor in an unpolluted water area, rejecting gravels from the kelp, immersing the kelp in deionized water for 20-25 h, air-drying the immersed kelp, drying the air-dried kelp in a blast air oven at 40-60 DEG C for 10-14 h, crushing and sieving the dried kelp, filling a ziplock bag with the obtained kelp powder, and storing the kelp powder in a drying box for later use; and 2, weighing a certain amount of the kelp powder in a tubular furnace, heating the tubular furnace to 350-450 DEG C, carbonizing the kelp powder, introducing water vapor from the top of the tubular furnace to fully activate the carbonized kelp powder, or carbonizing kelp which is impregnated in a chemical reagent in advance, cooling the obtained material to room temperature, allowing the cooled material to pass through an airflow conveying pipeline and enter a stainless steel high-pressure airflow crusher, refining the obtained biochar to form 1000-1500 mesh small-granularity particles, and aseptically packaging the sterilized kelp biochar in a food packaging bag in an aseptic operating environment.

Description

technical field [0001] The invention relates to a method for preparing edible biochar packets from kelp, a method for preparing edible biochar packets based on a natural active substance-kelp, and belongs to the technical field of food additive preparation. Background technique [0002] Charcoal has been used as an edible medicine since ancient times to treat diseases. After carbonization, the carbon molecular structure of biomass is quite stable, and generally does not react with weak acids and weak bases, so it will not cause side effects to the human body, is easy to excrete, and has no residue in the body. And after the human body ingests an appropriate amount of biochar, it can absorb toxins, regulate endocrine, detoxify and beautify the skin. Used as a food additive in the diet, it can absorb and decolorize, and the far-infrared rays released can evenly heat food such as rice, so the color of the food that can be cooked is more attractive, and the taste is softer and ...
