Savory Flavor Seasoning Spray Dryer

A savory flavor is a flavor used to enhance or impart a savory flavor to food. It is a complex mixture of ingredients whose main purpose is to mimic and intensify the flavor of savory ingredients such as meats, seafood, and vegetables, so that the food product acquires a richer, more authentic flavor during processing or cooking.With the continuous progress of the modern food industry, more and more processed foods emerge, such as instant noodles, puffed food, canned food, etc., these foods need to add savory flavors to enhance or simulate a variety of consumer favorite flavors, which promotes the growth of savory flavor market demand.Nowadays, consumers have higher expectations for the taste and flavor of food, and hope to enjoy a richer, more intense and realistic flavor experience. Savory flavors can meet this demand, whether in the casual food, convenience food or catering industry, have been widely used, which in turn contributed to the increasing market demand.

Spray Dryer for Savory Flavors and Seasonings Process Flow

(1) Liquid preparation: the savory flavor seasoning raw materials to be dried into a certain concentration, viscosity and fluidity of the liquid, and filtered to remove the impurities and insoluble particles, to prevent clogging of the atomizer.

(2) air filtration and heating: the air is first filtered through the primary, intermediate and high efficiency filters to remove dust, microorganisms and other impurities, to meet the hygiene requirements of food production. Filtered air into the heater, through steam, electricity, fuel oil or gas, etc. Heating to the set air temperature, generally 160 ℃ ~ 220 ℃ or so.

(3) Liquid atomization: The filtered and heated air enters the air distributor on the top of the dryer in a spiral shape. At the same time, the material liquid is transported to the centrifugal atomizer on the top of the dryer by the pump from the material liquid tank through the filter. In the centrifugal atomizer, the material liquid is thrown into very small fog droplets under the action of centrifugal force generated by high-speed rotation, which greatly increases the surface area of the material liquid in contact with the hot air.

(4) drying process: the atomized material liquid and hot air parallel flow contact, due to the large surface area of the droplets, moisture in the hot air stream instantaneous evaporation. The hot air will transfer the heat to the material droplets, so that the moisture is rapidly vaporized and taken away by the hot air, in a very short period of time (generally as long as 5 ~ 15 seconds) drying for the finished product.

(5) Finished product collection: part of the dried product is discharged directly from the bottom of the drying tower, and the other part enters the cyclone separator with the airflow. In the cyclone separator, the finished product and the exhaust gas are separated, and the finished product is collected into the powder collecting cylinder. In addition, in order to improve the recovery rate, can also be equipped with secondary dust removal devices at the outlet of the fan, such as bag filter.

(6) Exhaust gas discharge: the exhaust gas after separating from the finished product is extracted by the fan and discharged into the atmosphere after the exhaust gas treatment device meets the standard to meet the requirements of environmental protection. Tail gas treatment can be selected according to the actual situation, such as water film dust removal, wet electrostatic dust removal and so on.

(7) Cooling and packaging: the collected finished products may have high temperature and need to be cooled to prevent lumping and deterioration. Usually use cold air, attached to the wall under the material system or pneumatic conveying system in the dehumidification, purification, temperature control air on the finished product cooling and conveying, and at the same time play a role in mixing, and then the cooled finished product is transported to the clean collection of powder packing room, to reduce the cross-pollution of materials.

Spray Dryer for Savory Flavors and Seasonings Performance Characteristics

(1) High drying efficiency

Rapid drying:Centrifugal spray dryer can dry the liquid raw material of savory flavor seasoning into powder in a very short time (usually a few seconds to a dozen seconds). This is because it atomizes the material liquid into very small droplets through the centrifugal clouding apparatus, so that the contact area between the material liquid and the hot air is greatly increased.For example, the diameter of the atomized droplets can be as small as a few tens of microns, so small droplets can let the moisture in the hot air under the action of rapid evaporation, greatly improving the drying speed.

Continuous production: the equipment can realize continuous uninterrupted production process, as long as to ensure a stable supply of material liquid and suitable drying conditions, can continue to produce dried savory flavor products. This can effectively improve the production efficiency and meet the market demand for large-scale production of savory flavors and seasonings.

(2) Excellent product quality

Good particle uniformity:The savory flavor powder produced by centrifugal spray dryer has uniform particle size. This is due to the high speed rotation of the centrifugal atomizer so that the material liquid is uniformly dispersed into droplets, under the same drying conditions, these droplets can be synchronized drying, resulting in the formation of a more uniform particle size of the product.Savory flavors with uniform particles perform better in terms of solubility and flowability, for example, they can be dispersed more uniformly when added to food products, which is helpful for ensuring the consistency of food flavor.

Effective retention of flavor and nutrients: In the drying process, due to the parallel flow drying mode, the hot air and atomized material flow in the same direction, the moisture on the surface of the material evaporates quickly, so that the temperature inside the material particles will not be too high. This gentle drying method can minimize the damage to the flavor components and nutrients in the savory flavors and seasonings, ensuring the quality and taste of the product.

(3) High degree of automation

Easy to operate: The centrifugal spray dryer is equipped with advanced automatic control system. The operator can conveniently set and adjust the key parameters in the drying process through the control panel, such as air inlet temperature, air outlet temperature, atomizer speed, feeding speed, etc. The equipment can automatically run according to the set parameters and monitor the running status in real time. The equipment can run automatically according to the set parameters and monitor the operation status in real time, which reduces the frequency and labor intensity of manual intervention.

Fault warning and automatic protection:The automation system also has fault warning and automatic protection functions. When the equipment appears abnormal conditions, such as high temperature, abnormal pressure, motor overload, etc., the system will immediately issue an alarm and take corresponding protective measures, such as stop feeding, stop heating, etc., in order to prevent equipment damage and product quality accidents.

(4)Highly flexible

Adaptation to a variety of liquid characteristics: for different viscosity, concentration and composition of savory flavors and seasonings liquid, centrifugal spray dryer has a good adaptability. By adjusting the rotational speed of the atomizer, feed rate and drying parameters, it can successfully dry many types of liquids. For example, for the higher viscosity of the liquid, you can increase the rotational speed of the atomizer and the temperature of the air inlet to ensure good atomization effect and drying efficiency.

Adjustable product specifications:According to the market demand and product requirements, we can flexibly adjust the specifications of savory flavor products such as particle size and powder density. By changing the structure and operating parameters of the atomizer, it can produce products with different particle size distributions to meet the requirements of different food processing processes on the characteristics of savory flavor particles.

(5) Better environmental performance

Effective dust control:Dust will be generated during the drying process, centrifugal spray dryer is equipped with perfect dust collection system. These equipments can efficiently separate the dried finished product from the exhaust gas with high collection rate, effectively reducing the dust emission into the air, which not only reduces the loss of product, but also meets the requirements of environmental protection.

Convenient Exhaust Gas Treatment:For the exhaust gas generated during the drying process, the equipment can be conveniently connected with the exhaust gas treatment device. Through the use of appropriate exhaust gas treatment technology, such as washing, adsorption, etc., the odor and harmful substances in the exhaust gas can be treated, so that it meets the emission standards before discharge, reducing the pollution of the environment.
