a food dehydrator review - how to compare food dehydrator products and features - food dryer dehydrator
In evaluating and reviewing the food dehydrator, the following product features and functions of different units and brands should be considered and compared.
One way to compare different brands of food dehydrators with similar features is to evaluate food dehydrators at a price per square foot of dry area (
Total price divided by total dry area)
Also consider the brand, reputation and product reviews of the dehydrator unit being considered.
You can evaluate the different brands of food dehydrators that have different product features using the same price per square foot for the total dry area, then personally decide if the extra features are worth the extra cost per square foot.
Total dry or dehydrated areas-
How much space does it take to dry food?
The total dehydration area is expressed in square feet and calculated as follows: product of
The number of drying trays multiplied by the size of the drying tray (
Length (in inches)divided by b)
Square inch 144
For example, if the dehydrator has 9 dry pallets, 15 inch × 15 inch per pallet, then the total dry area is equal to 14. 1 square feet (
15 multiplied by 9 = 2,025, 2,025 divided by 144 equals 14. 1).
Obviously, the total dehydration area determines how much food you can dry at a time.
The total dry area should be enough to accommodate the maximum amount of food you will dry during 20 years
According to rough experience, the dry area per square foot can dry about a pound of food.
However, this amount varies depending on the type of food that is dry, the thickness of the food slice, and the moisture content of the food. o Air Flow -
The dehydrator removes moisture from food through heat and air flow.
The air flow of the food dehydrator is designed horizontally or vertically.
The heating elements and fans of the horizontal airflow food dehydrator are located on one side of the dehydrator.
A dry tray for placing food is like a drawer inside a food dehydrator.
Generally, the horizontal airflow dehydrator is better at dehydration of different types of food at the same time, because the horizontal airflow is better than the vertical airflow dehydrator mixed food taste.
In addition, the horizontal airflow dehydrator better prevents food juice from dripping onto the heating element, making cleaning easier.
The heating elements and fans of the vertical airflow dehydrator are located at the bottom of the dehydrator.
A dry tray for storing food is stacked on top of the base.
Because the dry tray and the food pile up on the top of the heating element, the drying temperature between the food drying tray at the top and bottom may vary.
During dehydration, vertical airflow dehydrator may need to replace the top and bottom drying tray in order to achieve a uniform drying effect on all food and drying trays. o Thermostat -
A thermostat is a device used to adjust the temperature of a heating or cooling system so that the temperature of the system remains near the required selected quantity.
The thermostat does this by turning on or off the heating or cooling system as needed to maintain the required temperature.
The adjustable thermostat for the food dehydrator should have a good range of drying temperatures, usually 85 to 155 degrees Fahrenheit, to handle different types and quantities of food.
A food dehydrator without a thermostat will dehydrate under constant heat, but the temperature inside the dehydrator may increase.
This may lead to hardening of the case;
Food that is dry outside but has moisture and potential bacteria inside. o Watts -
The energy consumed or used by the dehydrator is measured in watts, similar to the bulb.
The Watt power of the food dehydrator shall be related to the total dry area.
To ensure adequate food dehydration, more drying trays and larger dehydrator sizes should require more watts for dehydrator use.
You can compare the energy used or needed between different dehydrators by comparing the watts per square foot of the total dry area.
Simply divide the tile of the dehydrator unit by the total dry area to get the tile per square foot. o Price -
A good indicator of comparing different dehydrators is to compare the cost of their total dry area per square foot.
To calculate, divide the cost of the food dehydrator by the total dry area of the unit.
