Industriële multi-naald pekelinjectie: voor een gelijkmatige verbetering van vleesproducten (whole-muscle)
The BNI-48 Multi-Needle Brine Injector delivers curing brines, phosphate solutions, and flavored marinades deep into the structural center of whole-muscle meat cuts with a level of distribution uniformity that surface tumbling alone cannot achieve. Equipped with a 48-needle spring-loaded injection head operating across a 400 mm conveyor width, the machine penetrates thick pork loins, bone-in hams, chicken breast butterflies, and bacon bellies simultaneously from top to bottom. By controlling injection pressure independently from conveyor speed, operators precisely dial in target brine pickup percentages from 10 percent for light seasoning enhancement up to 45 percent for high-yield cooked ham production. The result is a product with consistent salt, moisture, and flavor distribution from the outer crust to the geometric core — eliminating the pale, under-cured center pockets and dark, over-cured surface bands that destroy batch uniformity in static soaking or single-needle operations.

注射機制:針對不同厚度設計的彈簧加壓穿透技術
整塊原肉的幾何形狀從來都不是規整一致的。例如,一條豬里脊從中心位置的 90 毫米到尾端的 30 毫米逐漸收窄;雞胸肉也從胸骨處的 45 毫米變細至翼尖處的 12 毫米。傳統的定行程注射頭無法根據肉塊厚度調整針頭深度,這會導致針頭直接刺穿較薄的部分,使鹽水噴濺到傳送帶上而非進入肉中,造成極大的浪費。BNI-48 則透過獨立的彈簧加載針頭懸掛系統,徹底解決了這一問題。
Alle 48 SUS316L-Nadeln sind einzeln auf jeweils kalibrierten Druckfedern innerhalb des Injektionskopf-Blocks montiert. Wenn der Kopf auf ein unregelmäßig geformtes Fleischstück absinkt, dringen die Nadeln, die auf dickere Partien treffen, bis zum vollen Hub ein. Treffen die Nadeln hingegen auf dünnere Stellen, werden sie durch den Widerstand der Federn abgebremst und stoppen an der natürlichen Unterseite des Fleisches. Nadeln, die das Fleisch gar nicht berühren, fahren vollständig zurück, wodurch keine Sole austritt. Diese adaptive Eindringgeometrie stellt sicher, dass jeder Tropfen der unter Druck stehenden Lösung direkt in das Muskelgewebe injiziert wird, ungeachtet der unebenen Oberflächenstruktur des Fleischstücks.
Precision Pickup Control: The Three Key Variables
- Injection Pressure:盐水泵以 0.05 至 0.4 MPa 的可调压力将溶液输送至针头歧管。较低的压力可实现温和的扩散式注入,适用于对压力敏感的鱼类和禽类,以免过大的液压导致纤维破裂或留下明显的针孔痕迹。较高的压力则能强力将含有悬浮香料颗粒的粘稠腌制液,均匀分布于腌制牛肉或五花肉致密的胶原基质之中。
- Conveyor Speed:由變頻器(VFD)控制的輸送帶決定了每塊肉在注液頭下停留的時間。輸送帶速度較慢時,每塊肉會經過多次針頭往復運動,從而增加注液總量;速度較快時,針頭往復次數減少,注液比例也會隨之降低。操作人員可直接透過 HMI 觸控螢幕,以每分鐘米數(m/min)為單位設定輸送帶速度。
- Stroke Frequency:De injectiekop beweegt verticaal in een programmeerbare cyclus van 40 tot 80 slagen per minuut. Samen met de snelheid van de transportband bepaalt deze parameter de fysieke afstand tussen de insteekpunten op het vleesoppervlak. Een kleinere afstand zorgt voor een gelijkmatigere verdeling, terwijl een grotere afstand acceptabel is voor producten waarbij de injectiesporen door het daaropvolgende roken of koken worden gemaskeerd.

Brine Recirculation and Filtration
Ved kontinuerlig injicering vil en betydelig del af den tilførte lage si gennem kødet snitflader og samle sig i transportbåndets opsamlingsbakke. BNI-48 opsamler dette overskud i den integrerede 200-liters lagertank i rustfrit stål, som er placeret under transportbåndet. En dedikeret recirkulationspumpe fører løbende den opsamlede lage tilbage gennem et flertrins filtreringssystem, før den genindsprøjtes i injektionsmanifolden. Filtreringsenheden består af en grov si i rustfrit stål (der fjerner knoglefragmenter og bindevæv over 2 mm) efterfulgt af en fin nylonfilterpose (der fanger fedtkugler og proteinstrimler over 0,5 mm). Denne lukkede recirkulationsløsning forhindrer tilstopning af dyserne, hvilket ellers ville medføre manglende injicering i produktet, samtidig med at det minimerer spild af lage og reducerer råvareomkostningerne.
Upstream and Downstream Process Chain
The brine injector is neither the starting nor the final stage of the curing process. Upstream, meat blocks are received from the primary portioning stations, tempered to an optimal injection temperature of 0 to 4 degrees Celsius, and then loaded onto the injector conveyor. Downstream, the injected pieces move directly into a真空式肉类滚揉机藉由機械式翻動作用,使注入的鹽水液滴均勻分布於肌纖維基質中,並萃取出表層肌球蛋白以強化結合力。這種「注射加翻動」的組合,是全球生產熟漢、醃製禽肉及增鮮整塊肌肉製品時,公認的標準兩階段醃製製程。BNI-48 能完美融入整套綜合製程之中。løsninger til kødforarbejdningsudstyrcovering the entire production chain, from the reception of raw materials through thermal processing to final packaging.
针头维护与卫生规范
The 48 SUS316L needles are the highest-wear consumable component in the system. Each needle features a side-port discharge design rather than a bottom-exit hole. Side ports distribute brine radially as the needle penetrates, creating a cylindrical saturation zone around the needle shaft rather than a concentrated pool at the needle tip. This significantly improves intra-muscular distribution uniformity. When a needle becomes blocked by hardened protein or a bent tip prevents smooth penetration, individual replacement takes under 30 seconds using a simple push-and-twist bayonet fitting. A complete 48-needle replacement set ships standard with every machine. For end-of-shift sanitation, the entire needle head block lifts off the machine frame on guide rails, and the brine tank drains completely via a bottom ball valve. All product-contact surfaces are accessible for direct scrubbing and hot water rinse within 25 minutes.
