Importance of lyophilizers for the production of yogurt
A freeze dryer is a machine in charge of the freeze drying process, also known previously as cryodrying, which is nothing more than the method of cold drying and subsequent sublimation of the ice of a material, which has been previously frozen. This process occurs because the water containing the product passes directly from solid state to vapor state, ignoring the liquid state. Freeze-drying is able to remove 99% of moisture from, for example, a food such as yogurt ferment, coffee, vegetables and fruits, among others, achieving great benefits in relation to the cost of transport, since, being a microbiologically stable product, a cold chain is not necessary and can be transported in greater quantity.
Freeze-dryers to conserve archeological artifacts
Freeze-drying is an equipment that works by making use of drying by vacuum freezing. The freeze-drying process, which is nothing more than an advanced dehydration procedure, removes all traces of water and moisture from the product and sublimes the ice, thanks to the low pressure to which it is subjected. Due to their incredible drying capacity, freeze-dried materials have a higher quality and benefits than dehydrated products through other processes.
What is a freeze dryer?
The lyophilizer is the apparatus used to carry out lyophilization. It consists of the following parts: dry chamber or lyophilization chamber: it is the place where the substance to be lyophilized is placed, condenser with a refrigeration circuit: it communicates with the dry chamber and it is where the vapor that is produced in the sublimation is condensed and finally a vacuum system.
Use of lyophilizers to conserve coffee
The lyophilizer is a device by which the process of lyophilization is carried out, which is nothing more than the drying of various materials. This equipment allows, through cold drying, the ability to remove moisture from a product or food to obtain it dehydrated, allowing them to continue conserving their properties and nutritional values, in addition to decreasing their volume.
How are Brix degrees measured with the refractometer?
Brix grades are defined as the percentage by weight of a pure sucrose solution, which measures 1 gram of sucrose per 100 grams of sample. The scale is based on the directly proportional relationship between the refractive index at 20°C and the mass percentage of total soluble solids of a pure aqueous solution of sucrose, i.e. 50° Brix equals a sugar content of 50%. This conversion is standardized by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA).
How useful is the veterinary refractometer?
Refraction is the change in the velocity of a wave that affects a surface as it passes from one medium to another with a different refractive index. The refractive index is the ratio of the speed of light in vacuum to the speed of light in another substance, making the refractive index a specific physical property. This parameter of analysis is a good approximation for media where losses by absorption or other phenomena are negligible.
What are the advantages of using wheelchairs?
The wheelchair is a technical instrument used by all those who have motor disabilities related to the loss of locomotion, or who have reduced mobility, either as a result of injuries, psychological illness, or physical illness such as paraplegia or quadriplegia, among others. Because this equipment is made of lightweight and resistant materials, the user can fold, lift and store it.
Anemia detection with the use of Electrophoresis
If the proportion of red blood pigment and/or red blood cells in the body is too low, there is anemia. The iron-containing protein hemoglobin (Hb) is the most important ingredient in red blood cells and is responsible for the transport of oxygen from the lungs to the cells of the body.
Functions of pH Ion Meters in the Cosmetic Industry
In the manufacture of cosmetic products there are three essential aspects that must be addressed, the first, the elaboration of products pleasant to the touch and to the smell. The second is that they are efficient, that is, that these products improve the condition of the skin or hair and do not cause unfavorable effects. The third, that the shelf life declared on the packaging is met.
How is water hardness determined with Calcium Ion Meters?
Water hardness refers to the amount of calcium and magnesium dissolved in water. The term comes from the ability of water to consume soap and is linked to how difficult it is to wash with this type of water. When soap is mixed with hard water, the minerals are combined with soap and form a solid precipitate, which decreases the cleaning efficiency of the soap.
