“E-jen” Vacuum and Airtight Storage Container

1. Principle of E-jen Vacuum and Airtight Storage Container

   To store foods for a long time, we have to protect them from being perished and there are four factors playing a role in perishing such as 1) temperature, 2) moisture, 3) nutritive elements and 4) air.

   If one of these factors is insufficient or doesn't exist, the putrefaction never happens or goes slowly.

   One of the best way to store food is containers like canned goods or cans.

   The canned goods are available to store foods for a long time for storing foods in vacuum state but they can be used just one time.

   If there is a container providing vacuum like cans and is able to use several times, it will be an outstanding one.

All the containers as we know are composed of bodies and lids. All of them have air layer with the same size of the contents (HEAD SPACE) and the more we pull contents out of containers, the bigger head space and this makes molds or deteriorate the original taste of food by bad microbes in the air. E-jen has vacuum plate (pressing plate) in the middle of the container and movable upward and downward. If you press the plate close to the food inside, the air in the container becomes minimized and blocks air flowing from the head space so it has very similar effect to cans. E-jenhas silicon packing inserted along the edge of the vacuum plate. The pressing mechanism of the vacuum plate improves the insulation of the silicon packing and has the following features.

1) preserving perishable food in a container

2) compacting food 

3) preserving perishable food in a vacuum state

The e-jenis a preservative container with the same benefits of canned food

in the utility sense of being a container,  compactor and preserving the

contents in a vacuum state.

1. The E-Jen is a storage science based on the rule of zero-stale smell, zero-mold, zero-top layer and zero-air.

2. The E-Jen is not allowing air in to keep the food fresh for a long time.

The inner lid of the E-Jen extracts all air from the space under the inner lid to prevent the mold, an aerobic microorganism living in the presence of air, from being reproduced on the surface of the soybean paste (Doenjang) and the hot pepper paste (Gochujang). No stale smell or a top layer is found in Kimchi and pickles stored in the E-Jen. Based on the same principle of the canned goods that are preserved in vacuum, the E-Jen is able to maintain the vacuum inside continuously during the storage. 

3. The E-Jen keeps a unique taste of the food twofold.

Enjoy the taste of the carbonated water of Kimchi and Watery Radish Kimchi, which cannot be expected from

those stored in a common container.

4. The E-Jen keeps the flavor of food from the beginning to the end of the storage. The E-Jen extracts all air from inside to prevent the food from being over-fermented, turning sour, and browning.

5. The E-Jen is a smart taste guard to keep fruits and vegetables fresh, and prevent the dried seaweeds and cookies from becoming damp.

7. Available for any use at any location, including refrigerator, freezer, indoor and outdoor
