Lyophilization - The Freeze Dryer Driven Food Revolution

 

Ever since the dawn of time, people have tried to find ways to ensure that food remains safe to store and consume for the longest possible time. In the last few years, the revolution in long term food storage has been let by the process of Lyophilization. In this process, the food is frozen below its triple point and then dried through vacuum process to extract all moisture from food and disperse it elsewhere. This process is done to kill all bacteria and other microbes present in the food item. Once all the microbes are destroyed, the food spoilage process slows down to such an extent that it can be stored safely for very long duration of time. 

Three Step Process:

·        The first step in the process is to freeze the product at a very fast pace. Yatherm freeze dryer is specially prepared to ensure that no ice crystals are formed in the food which may risk insufficient drying activity.

·        The second step is to expose the item to a vacuum which is placed below the triple point of water to extract any moisture which may be left after the freeze steps. This leads to moisture becoming consolidated which is then ready for the next step.

·        Finally, the material is dried out through sublimation which leads to all the consolidated moisture content being sucked out of it and dispersed elsewhere. 

Key Features of Freeze Dryer:

Freeze dryer equipment is designed to be extremely user friendly. The device is equipped with digital PID controller and multiple validation ports. No CFC or HCFC is used in refrigeration to ensure that environment is not impacted at all. The devices have the capability to operate from below -40°C or -110°C temperature and operate in single and dual stage cooling. Devices are available in different ice capacities from 2 to 50 litres.

The machines are fitted with Temperature, pressure and time control system and handles both primary and secondary drying steps with ease. The body is built to resist any kind of corrosion. The display panel is also equipped with an audio-visual alarm system on its display panel for single point monitoring..

The Future of The Freeze Dryer:

The food industry has a bright future because despite all scientific process, there is no alternative to eating and many food items need to be shipped and stored for a long duration. Similarly, with growing economic power of people, choice and quantity of food demand is also expected to grow exponentially. People are looking for more internationally available food items and a global culinary palette is emerging.

This can only be satisfied by freeze dryers which will allow long storage and shipping of food. Lyophilization is a mature technology and can be scaled and adopted very rapidly. It has minimal impact on taste, shape, colour and texture of the food. Yatherm freeze dryer is a cost effective and highly durable product ready to match the growing demand of such products all over the globe.

BIOLOGICAL SAFETY CABINET: USE, DISINFECTION AND WORK

Biological Safety Cabinet (CSB), commonly known as biosafety cabins (cabinet), are part of a group of teams aimed at improving the general conditions under which a wide variety of activities are carried out in clinical and research laboratories in the area of public health. These activities range from routine processes for the identification of microorganisms to specialized research activities. Likewise, they are also known by various names such as "biosafety cabinets", "laminar flow hoods" and "purifiers", among others, the term "laminar flow" is also commonly used to identify them. The equipment is what guarantees the existence of controlled environments, essential for activities that, due to their characteristics, are potentially dangerous for the health of man and the environment. On the other hand, some of the cabins protect the state of the products or crops under investigation.

What Is And How Does A Biological Safety Cabinet Work?

Biological Safety Cabinet is equipment designed to maintain an area, free of particles or probable contaminants that can alter the product or process with which it works, affect the health of the operating worker, or damage the environment.

The conditioning of the clean area is achieved by combining electromechanical elements (motor, fan, filter, ducts, lighting, etc.), and physical processes (laminar flow, pressure differential).

In this way, the fans propel the air through special filters of great surface, strategically located, that have a minimum efficiency of retention of particles of 99.99%, when the size of the same is on average of 0.3 μm (micrometers). Such filters are known internationally as HEPA filters and are suitable for retaining aerosols that are generated when experimental procedures are performed with biological agents such as agitation, centrifugation or mixing.

While there are different types of Biological Safety Cabinet (CBS) defined based on different types of biosecurity levels, all CBS are designed to provide protection to the operator and the environment.

Under this premise is that we consider it necessary, beyond the normative, to be able to guarantee the correct functioning of these equipment.

When a device with these characteristics is acquired, it is usually done thinking about the type of process. However, if we do not have certain considerations about the physical space it will occupy, the environmental conditions of the immediate environment, and the characteristics that apply to its proper functioning, we may not be operating the equipment safely.

Generally the Biological Safety Cabinet is constructed of steel, have a front window in glass, of variable height that has a ventilation system consisting of an electric motor, a fan and a set of ducts that, when being operated, generate a condition of negative pressure inside the cabin compared to the ambient pressure in the laboratory, a condition that causes air to flow inside the cabin through the front opening, generating an air curtain that protects the operator. Internally, the air is conducted through a series of grilles and ducts, to finally be treated by HEPA filters.
