RU2606811C1 - Drier for blue-green algae - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention relates to agricultural machine building. Drier for blue-green algae comprises a loading hopper, an auger elevator, air heater. On longitudinal cylindrical surface of auger there are spiral strips with mesh surface with possibility of changing direction of movement and rotational speed of auger. Air heater is configured for changing temperature mode of air heating. Along perimeter of auger elevator there are air distributors.

EFFECT: invention provides faster drying process due to blowing algae with heated air through mesh surface of spiral strips of auger, wherein starting material is subjected to intensive turning.

Description

The invention relates to agricultural machinery, in particular, can be used to create drying equipment for algae.

In the design of known algae dryers, furnaces with a furnace are used as air heating, while the process of maintaining the temperature regime of drying algae in a predetermined range is difficult, which negatively affects the compliance of the dried material with agricultural requirements and product quality. In this regard, drying was not widely used.

Algae dryers are also known, the design of which is based on the principle of centrifuge operation.

In the aggregate of common essential features, the technical solution patent RU No. 105118 U1 А01D 44/00 is taken as a prototype.

The disadvantages of the known devices.

1. Dryers do not dry algae.

2. The temperature mode of drying is not supported in the specified range.

The objective of the invention is the improvement of the technological process of drying algae with the possibility of their further application.

The task is performed by a screw elevator, on the longitudinal surface of which spiral strips with a mesh surface are fixed, with the possibility of changing the direction of rotation and speed of rotation of the screw, and the air heater is made with the possibility of changing the temperature regime of heating the air, with air distributors installed around the perimeter of the screw elevator.

EFFECT: algae drying process is improved, and dried algae comply with regulatory requirements for their storage.

The technical result is achieved by using spiral auger tapes in the dryer design as a mechanism for moving the starting material and as a tedder in the process of drying algae, while the mesh surface of the spiral tapes allows heated air to penetrate the algae layer, ensuring their active ventilation, and to carry out the drying process in a given mode. This makes it possible to obtain algae in dry form that meets the regulatory requirements for storage, and the possibility of their use for human needs.

The noted positive aspects of the claimed object allow to obtain an economic effect and wide distribution in the system of ecological safety of the environment.

The drawing schematically shows a dryer for algae.

The dryer contains a cylindrical cavity 1 of a screw elevator, a screw 2 with spiral belts 3 with a mesh surface, an air heater 4, a hot air distributor 5, air channels 6, a loading hopper 7, an auger drive motor 8, wheels for movement 9, a container 10.

The dryer operates as follows.

Blue-green algae in the initial phase of their development, when their size is insignificant, to be disposed of, are loaded into the hopper 6, then the motor 7 is turned on, while the screw 2 rotates and fills the screw cavity 1, and at this time the air flow distributor 5 is fed through air channels 6 heated air, which blows algae from all sides, including penetrates the algae through the mesh surface of the spiral tapes 3, while improving the drying process. Having achieved the necessary shrinkage, the algae in the dry state are discharged into the container 10, the large algae are crushed into smaller fractions before drying.
