Vegetable storage ventilation device

Heating and insulation are essential components of a well-maintained, energy-efficient home. Proper ventilation for vegetable storage is another factor that’s equally important but is frequently disregarded. The quality and shelf life of your veggies can be greatly extended by having a well-designed ventilation system, whether you’re a passionate gardener or just like eating fresh produce.

Imagine packing your bags full of vibrant carrots, crisp lettuce, and juicy tomatoes for your trip home from the farmers’ market, only to discover them wilted and spoiled in a matter of days. We’ve all felt disappointment in this. However, you can increase the length of time your vegetables stay fresh and flavorful by installing the proper ventilation system.

Vegetables have been kept cool and dry for centuries through the use of traditional storage techniques like root cellars. Even though they work well, they frequently take up a lot of room and might not be appropriate for contemporary homes. This is where cutting-edge ventilation systems come into play, providing a portable and effective way to preserve your crop.

These gadgets provide the ideal storage environment for vegetables by regulating humidity and airflow. They keep the produce from getting too wet and stop bacteria and mold from growing by forcing air around it. By doing this, you can enjoy your veggies at their freshest for longer, while also preserving their nutrients and flavors.

Ventilation of the vegetable store

When designing potato storage, the ventilation system should be taken into account. The selection of air exchange in the room is influenced by the following factors:

• What vegetables are laid for storage;
• vegetables are placed in containers or scattering;
• the dimensions of the hangar;
• The potato storage is equipped with heating or not;
• The material of the walls of the vegetable store.
• The design of the structure.

Crucial! Vegetables are exposed to heat and moisture when they are being stored. When humidity levels in vegetable stores are not met, potatoes and other vegetables start to rot. GOST 2489-44 states that while storing onions up to 85%, the humidity in potato storage facilities is said to be between 80 and 90%. Mixed vegetable storage should be done at a humidity level no greater than 95%. Either forced or natural ventilation must be established in order to reach this standard.

Natural air circulation in the room

The lower section of the front wall houses the potato storage facilities, natural ventilation systems, and supply and output ducting and valve systems. The vegetable store’s side walls and exhaust mines under the roof are suitable places for installation. A manual regulator used to supply air will result in consistent blowing. A crop of vegetables is blown out by airflow that enters from below. It is then released via the mine.

The pressure differential between the inside and outside of the structure causes this kind of air exchange. The air moves more slowly during the warm season, making the "stagnation" apparent. It is worthwhile to create a combined type of ventilation in order to prevent such situations.

Maintaining freshness and avoiding spoiling in vegetables requires adequate ventilation during storage. Our novel ventilation device provides an easy-to-use yet efficient answer to this frequent problem. Our gadget contributes to temperature and humidity regulation, which creates the ideal environment for extending the shelf life of fruits and vegetables by uniformly moving air throughout the storage area. Our system is energy-efficient and simple to install, and it is made to accommodate the requirements of commercial and small-scale vegetable storage facilities. Our vegetable storage ventilation device allows you to say goodbye to wilted produce and hello to longer-lasting freshness.

Forced ventilation in a vegetable storehouse

The most widely used potato ventilation system is this one. The following mechanical parts and devices are part of it:

• Remote Control;
• ceiling fans;
• humidifiers;
• circulation mechanical devices;
• exhaust ducts;
• mixing chamber;
• supply ventilation;
• supply fans;
• Support valves.

Forced ventilation device circuits

Method #1

Design utilizing channels and pressure walls (boxes, modules). This choice is used to store other vegetables, such as potatoes, in embankments. a maximum height of five meters. "Spent air" is mixed with the supply air as it enters the mixing chamber. After that, it passes through the pressure walls and enters the storage of vegetables based on floor-mounted ventilation systems. Consequently, there is a potato embankment.

You can choose spherical or triangular air ducts. It’s critical that they be able to support the weight of the vegetable embankment. The shutters and a moisture sensor are installed beneath the ceiling. They are responsible for the excretion of "spent air," which is a mixture of CO2 and ethylene.

A circulation pump is used to recirculate air once fresh air has been captured. The intake damper opens briefly to allow supply air to enter. Ceiling fans are responsible for the heating of the supply flows. On both sides of the pressure walls are air moisturizers installed. They forbid root crops from straying.

Method #2

Ventilation of the potato storage according to the second scheme, with supply and reaction blocks, easier. In its design it is not so bulky. Supply air streams, come and mix in air mixing chambers. Then the air enters the supply ventilation pipe to vegetables. After blowing it, it is stretched through the exhaust shutters outside the room. The damper can partially or completely overlap the air duct, so it plays the role of recirculation, supply valve. While in a horizontal position, it lets out the supply air, while the “worked out” is excreted out. Когда заслонка находится под наклоном, в приточный канал, частично попадает отработанный воздух. The vertical position is recirculated in air flows in the ventilation system.

Requirements for air ducts

It is advisable to refer to the set of regulations "buildings and premises for storage and processing of agricultural products" when assembling a ventilation project in a potato storage. 2011 in Moscow. Potato storage facilities will have 1.5 mm thick stainless steel air-tanking channels installed. 25 mm wave height. One section’s height ranges from 110 to 167 mm. Because air ducts are made in the shape of a half-pipe, assembly is made simpler. One section’s maximum weight is 47 kg, and its minimum weight is 12.0 kg.

The fact that the air ducts were perforated is significant. This makes using embankments to store vegetables easier. It is possible to design a ventilation pipe of any length using external characteristics. This method works well for installing ventilation in potato storage facilities of any size. The most important thing to remember when installing a ventilation system in such rooms is to follow the updated version of SNiP 2.10.02-84.

Since every hole in the ventilations is the same, air can flow freely in all directions. Disassembling the air duct is also practical when the vegetable storehouse’s supply of vegetables runs out. The air duct’s sections are suited for one-to-one folding, which greatly reduces the amount of storage space needed. You don’t need the assistance of experts to install the air duct system when the new crop season arrives if you can do it yourself.

Maintaining freshness and flavor in vegetables requires proper storage conditions. Using a ventilation device made just for this purpose provides a cost-effective and environmentally friendly solution.

First of all, by improving air circulation in the storage space, this device lowers the likelihood of mold and rot by preventing moisture buildup. It helps control temperature and humidity, two important aspects of extending the shelf life of vegetables, by ensuring adequate ventilation.

Moreover, by reducing the requirement for refrigeration, a vegetable storage ventilation device enhances energy efficiency. The device uses natural airflow to maintain ideal storage conditions rather than depending only on mechanical cooling techniques, which can be expensive and environmentally harmful.

This technology is also accessible to a broad range of households and agricultural operations due to its ease of installation and maintenance. It is a desirable choice for home gardeners and small-scale farmers who want to prolong the shelf life of their produce because of its low cost and simplicity of use.

To sum up, using a vegetable storage ventilation device is a sensible and environmentally friendly way to preserve produce. Through enhanced air circulation, temperature and humidity control, and decreased dependency on refrigeration, this technology provides an economical and sustainable means of guaranteeing the freshness and caliber of vegetables that are stored.
