#oven drying

[feralfens]

got fruit you love but worry about it rotting before you get the chance to eat it?

no problem! oven drying is an option!

cut the fruit of your choice to a little less then an inch. try to keep them all even but if theyre not thats okay, youll just have to do size specific batches.

if youve got skewers, stick em on the skewers. this is so you can hang the fruit between the ovens bars or on a tall cooking pan, which helps with drying evenly.

put oven on keep warm and carefully put them in. with my oven i havent burned myself on the keep warm setting (for me its 170 f), but that could be different for others. the point of using the keep warm setting is so that its at a low enough heat that the fruit dries out but is not baked.

ones the fruits in, its mostly just waiting and checking every couple hours. depending on the size of the fruit, itll usually take more than an hour. and its okay to leave them in there over night or when you leave the house for work/school/whatever with the oven off, since the same process is still happening but slower. still gonna get tasty dried fruit!

munch! you can eat your tasty fruit at your own pace!

How is drying technology used in the pharmaceutical industry?

In the pharmaceutical industry of China, spray technology is widely used, especially in the field of oral solid preparation, which is often used in the process of high heat sensitive drugs and liquid concentrate. The product has fine particle size, uniform, fluidity and instant solubility.

Basic flow of spray drying.

The liquid is atomized by the atomizer, dispersing into the dry cavity with tiny droplets. Meanwhile, the heating gas is fed into the heater by the blower, and then enters the drying chamber. The spray droplets and hot gases are fully mixed and touched in the drying chamber. The liquid in the droplet vaporizes instantly into a gas, and the material dries into fine particles.

The mixed gas-solid two phase is induced by the fan suction cyclone separator, the two phase separation, the solid material settling to the bottom of the collector, gas phase is sent to the dust filter, the collection and escape material. After the condensation of the gas phase, the solvent in the gas phase is changed into a liquid, which can be collected and applied. As the carrier gas is dried, it is recycled in the system.

Characteristics and classification of spray dryer.

Spray dryer is the drying equipment which directly dries the solution or suspension into solid particles. The dry product can be directly obtained from the feed liquid, eliminating the unit operation such as evaporation, crystallization, separation and pulverization, which can be continuous, automatic production and stable operation. In this drying method, the gas-solid two-phase contact surface area in spray dryer is large, and the drying time is short, suitable for dry heat-sensitive materials. The dry products are of good quality and can be obtained from 30 ~ 50 m particles with good fluidity and instant solubility. The disadvantage is that the volume of the drying oven is large and the heat transfer coefficient is low, resulting in low thermal efficiency and high power consumption.

There are many kinds of classification methods of spray dryer, which can be divided into flow type, counter-current and mixed flow according to the flow direction of gas flow. According to the installation mode of the atomizer, it can be divided into upper and lower spray type. According to the structure of atomizer, it can be divided into centrifugal type, pressure type and air flow type. According to the heating gas cycle can be divided into open, partial circulation and closed.

What drying oven is used for vegetable and fruit drying?

The difference between the heat pump drying equipment and the traditional hot air drying is that the air circulation is different, and the air in the drying chamber is wet in different ways. Heat pump drying drying technology is the use of refrigerant in the evaporator vacuum evaporation, the evaporator surface temperature is lower than the indoor air dew point, the endothermic temperature picks up after discharge in dry state, mixed with into indoor air, which reduces the indoor air humidity, achieved the purpose of drying dehydration.

At present, the dehydrated vegetable production mostly adopts the traditional drying method -- the drying method of drying oven is heated by the fire way, which has the following problems:

1. The heating temperature is too high. Traditional process drying technology, heating temperature is not easy to control.

2. The drying time is too long, and occasionally it is reheated and dried due to the poor drying effect.

3. Great energy consumption. The traditional drying process, the thermal efficiency is low, the dry material takes away the heat and the dryer heat loss more.

And heat pump drying equipment is dehydrated vegetable production line, no noise pollution, environmental protection, save operating cost, dry materials in the process of deformation, discoloration, not bad, dry thoroughly, less loss of nutrients, therefore has been widely applied to the tobacco drying, dragon fruit, raisins, litchi, longan, slag, red jujube, walnut, Chinese wolfberry, etc. Because this process USES the air circulation, the heating temperature is low, the drying time is short, the capacity is large. Therefore, the heat pump drying process consumes less energy and is a good energy-saving product.

Hot air oven baking method.

1, if you are prepare the material of a vehicle, such as tray and the rack, so you have to note that the problem of ventilation, should make sure to leave space for air flow, because love need to pack up and down through the material are all baking, so try not to take the material compaction and airtight.

2. The materials placed on the pallet should be kept as close as possible, so as to avoid the uneven baking of each part.

3 different material, high temperature blast drying oven roasted, appearance and inner quality after drying tuning have been baking time, dehydration rate of speed, the influence of temperature and humidity, so it requires the user to summarize the experience in the use of practice constantly, so as to get the best effect.

4, because different material surface and its internal structure is different, so the surface of the water loss rate during baking and internal water exosmosis rate are different, so we need according to the structure characteristics of the material and combined with the surrounding environment comprehensive factors such as temperature, humidity and wind speed, finally to determine the material need to use the drying speed, if rushed sometimes instead of long time needed for completely dry.
