技术领域 technical field
本发明涉及一种液氮冷冻设备，具体涉及利用液氮对鱼类产品进行冷冻的鱼类产品快速冷冻设备。 The invention relates to a liquid nitrogen freezing device, in particular to a quick freezing device for fish products that uses liquid nitrogen to freeze fish products.
背景技术 Background technique
鱼类产品冷冻是指利用低温条件抑制鱼类产品自溶作用酶的活性和附着微生物的繁殖，并减缓其脂质氧化、非酶性褐变等化学反应速度，使之在贮藏期间能保持优良品质的低温保鲜方法。鱼类产品冷冻大致包括冷藏保鲜和冻结保鲜两类方法，其中冻结保鲜法主要是先通过冷冻设备对生鲜鱼类产品进行速冻。液氮冷冻设备因其具有能快速冷冻产品、渡过冰晶生成带，防止大冰晶在食品细胞内的形成破坏细胞壁，较好的保持产品原有的风味和质量的特点，使其成为目前鱼类产品冷冻中的一种优越的冷冻设备。液氮冷冻工艺通常采用将液氮直接喷洒到鱼类产品上，使鱼类产品达到快速冷冻的目的。 Freezing of fish products refers to the use of low temperature conditions to inhibit the activity of autolytic enzymes and the reproduction of attached microorganisms in fish products, and to slow down the chemical reactions such as lipid oxidation and non-enzymatic browning, so that they can maintain good quality during storage. High-quality low-temperature preservation method. The freezing of fish products generally includes two types of methods: refrigeration preservation and freezing preservation. Among them, the freezing preservation method mainly uses freezing equipment to quickly freeze fresh fish products. Liquid nitrogen freezing equipment has the characteristics of being able to quickly freeze products, pass through the ice crystal formation zone, prevent the formation of large ice crystals in food cells from damaging the cell wall, and better maintain the original flavor and quality of the product, making it the current fish A superior freezing equipment in product freezing. The liquid nitrogen freezing process usually uses liquid nitrogen to be sprayed directly on the fish product, so that the fish product can achieve the purpose of rapid freezing.
目前的液氮冷冻设备通常分为柜式及隧道式液氮冷冻设备，其中隧道式液氮冷冻设备采用传送带对冷冻产品进行传送，并在传送过程中对鱼类产品进行冷冻，其适用于大批量的鱼类产品冷冻生产；但目前的隧道式液氮冷冻设备存在以下不足：由于鱼类产品在传送带上传送的过程中，鱼类产品通常保持一种固定不变的位置状态，使得鱼类产品两侧中的某一侧面始终贴合在传送带上；而液氮冷冻设备的液氮喷头通常设置在传送带的上方和/或一侧,这导致鱼类产品在整个冷冻过程中始终有部分表面无法被液氮直接喷到，使得鱼类产品的这个部位难以快速冷冻不仅延长了该部位的冷冻时间，而且难以保持鱼类产品原有的风味和质量；从而降低鱼类产品的整体冷冻效率及冷冻质量。 The current liquid nitrogen freezing equipment is usually divided into cabinet type and tunnel type liquid nitrogen freezing equipment. The tunnel type liquid nitrogen freezing equipment uses a conveyor belt to transport frozen products and freeze fish products during the transmission process. It is suitable for large Batches of fish products are frozen and produced; but the current tunnel-type liquid nitrogen freezing equipment has the following disadvantages: because the fish products are usually kept in a fixed position during the process of conveying the fish products on the conveyor belt, making the fish One of the two sides of the product is always attached to the conveyor belt; and the liquid nitrogen nozzle of the liquid nitrogen freezing equipment is usually set on the top and/or one side of the conveyor belt, which causes the fish product to always have a partial surface during the entire freezing process. It cannot be directly sprayed by liquid nitrogen, which makes it difficult for this part of the fish product to be quickly frozen, which not only prolongs the freezing time of this part, but also makes it difficult to maintain the original flavor and quality of the fish product; thus reducing the overall freezing efficiency and Frozen quality.

本发明的鱼类产品快速冷冻设备的具体工作过程如下： The specific working process of the fish product quick freezing equipment of the present invention is as follows:
第一，将鱼类产品由喂料斗喂入上传送带上，上传送带带动鱼类产品沿上传送带往下传送带方向传送；在这个过程中当鱼类产品穿过拨动板时，拨动板先将堆置在上传送带上的水产品铺散开，并使鱼类产品呈单层铺置在上传送带上，避免水产品叠置在上传送带上，影响鱼类产品的快速冷冻。（而在鱼类产品穿过拨动板过程中，柔性拨动装置中的配重块可以增加拨动板的拨动力度，有利于将水产品铺散开；柔性拨动装置中的拨动板可转动则可以避免鱼类产品卡死在拨动板与上传送带之间。) First, feed the fish products from the feeding hopper to the upper conveyor belt, and the upper conveyor belt drives the fish products to be conveyed along the direction of the upper conveyor belt to the lower conveyor belt; during this process, when the fish products pass through the toggle plate, the toggle plate first Spread the aquatic products stacked on the upper conveyor belt, and lay the fish products on the upper conveyor belt in a single layer, so as to prevent the aquatic products from stacking on the upper conveyor belt, which will affect the rapid freezing of fish products. (In the process of fish products passing through the toggle plate, the counterweight in the flexible toggle device can increase the toggle force of the toggle plate, which is conducive to spreading the aquatic products; the toggle in the flexible toggle device The rotatable plate can prevent fish products from being stuck between the toggle plate and the upper conveyor belt.)
接着，通过上液氮喷组的上液氮喷头将液氮直接喷洒到鱼类产品表面上进行冷冻。 Then, the liquid nitrogen is directly sprayed onto the surface of the fish product through the upper liquid nitrogen nozzle of the upper liquid nitrogen spray group for freezing.
第二，当上传送带将鱼类产品传送到翻身机构处后，鱼类产品将沿导向弧板往下滑动到翻身弧板上，并由翻身弧板滑落到过渡导向传送机构的倾斜传送轨道上；而在上传送带传动过程中，各传动摩擦轮将上传送带的动力传递到倾斜传送轨道的输送辊上，使各输送辊转动，并且使倾斜传送轨道的传动方向与上传送带的传动方向相同；这样鱼类产品被传送到倾斜传送轨道上后可以顺利的传送到下传送带上，避免鱼类产品的堆置、聚集； Second, when the upper conveyor belt transfers the fish products to the turning mechanism, the fish products will slide down along the guide arc plate to the turning arc plate, and slide down from the turning arc plate to the inclined conveying track of the transition guiding transmission mechanism ; And in the transmission process of the upper conveyor belt, each transmission friction wheel transmits the power of the upper conveyor belt to the conveying rollers of the inclined conveying track, so that each conveying roller rotates, and the driving direction of the inclined conveying track is the same as that of the upper conveying belt; In this way, fish products can be smoothly conveyed to the lower conveyor belt after being conveyed to the inclined conveying track, so as to avoid stacking and gathering of fish products;
在这个过程中，当鱼类产品由导向弧板滑落到翻身弧板上后，将完成鱼类产品的翻身动作使鱼类产品原本朝下的一面（与上传送带贴合的一侧）往上翻转成为朝上；这样当鱼类产品由倾斜传送轨道传送的下传送带上后，原本与上传送带贴合的鱼类产品表面将朝上，使得下液氮喷头喷出的液氮可以直接喷到鱼类产品该侧面，这样鱼类产品的各个部位的表面上都能够直接被液氮接喷到，从而有效解决现有技术中的隧道式液氮冷冻设备在冷冻水产品过程中因水产品的某一部位始终贴合在传送带上，导致水产品的该部位难以保持原有的风味和质量，降低水产品的冷冻效率及整体冷冻质量的问题，提高水产品的整体冷冻效率及冷冻质量。 In this process, when the fish product slides from the guide arc plate to the turning arc plate, the turning action of the fish product will be completed so that the side of the fish product that is originally facing downward (the side that is attached to the upper conveyor belt) is upward Flip to face up; in this way, when the fish product is conveyed by the lower conveyor belt on the inclined conveyor track, the surface of the fish product that was originally attached to the upper conveyor belt will face upward, so that the liquid nitrogen sprayed from the lower liquid nitrogen nozzle can be sprayed directly onto the The side of the fish product, so that the surface of each part of the fish product can be directly sprayed with liquid nitrogen, thereby effectively solving the problem of the tunnel-type liquid nitrogen freezing equipment in the prior art due to the freezing of aquatic products. A certain part is always attached to the conveyor belt, making it difficult for this part of the aquatic product to maintain the original flavor and quality, reducing the freezing efficiency and overall freezing quality of aquatic products, and improving the overall freezing efficiency and quality of aquatic products.
当鱼类产品输送到导向弧板与翻身弧板之间后，若水产品（鱼）被卡死在导向弧板与翻身弧板之间时；防堵塞调节装置可以使翻身弧板绕其转轴往外转动扩大导向弧板与翻身弧板之间的间距，从而释放被卡死在导向弧板与翻身弧板之间的鱼类产品，保证鱼类产品顺利的进行输送。 After the fish products are conveyed between the guide arc plate and the turning arc plate, if the aquatic product (fish) is stuck between the guiding arc plate and the turning arc plate; the anti-blocking adjustment device can make the turning arc plate go out around its rotation axis The rotation expands the distance between the guide arc plate and the turning arc plate, thereby releasing the fish products stuck between the guide arc plate and the turning arc plate, so as to ensure the smooth conveying of the fish products.
第三，鱼类产品由倾斜传送轨道传送的下传送带上，鱼类产品沿下传送带传送，在这个过程中下液氮喷组的下液氮喷头将液氮直接喷洒到鱼类产品表面上进行冷冻。 Thirdly, the fish products are conveyed on the lower conveyor belt by the inclined conveyor track, and the fish products are conveyed along the lower conveyor belt. freezing.
接着，完成冷冻后的鱼类产品落入回收框内。 Then, the frozen fish products fall into the recycling box.
