As traditional Chinese medicine (TCM) manufacturing and botanical extraction move toward standardization and regulatory compliance, drying has become a critical area for technology upgrades because it directly affects product yield, retention of active ingredients, and batch-to-batch consistency. To address the low softening point and high hygroscopicity of TCM extracts, Jiangsu Longxin has developed the ZLPG-5 Herbal Extract Spray Dryer Test System. Its systematic design incorporates anti-wall-adhesion, moisture-protection, and precise temperature-control features, providing pharmaceutical and food companies with verifiable equipment support for R&D trials, formulation screening, and process optimization.<\/p>\n\n\n\n

D\u00e9fis li\u00e9s au s\u00e9chage et \u00e9volution des exigences r\u00e9glementaires : mat\u00e9riaux \u00e0 faible point de ramollissement et hautement hygroscopiques<\/h2>\n\n\n\n

TCM extracts naturally have low softening points and high hygroscopicity.<\/p>\n\n\n\n

(1) TCM extracts are rich in sugars. The polyhydroxy structures in these molecules readily bind with water molecules in the air, making the dried powder highly prone to moisture absorption.<\/p>\n\n\n\n

(2) The feed liquid has high viscosity, creating significant challenges in atomization and powder collection during spray drying.<\/p>\n\n\n\n

(3) When conventional spray dryers are used to process such materials, caramel-like powder often adheres to the drying-chamber walls and the collection bin beneath the cyclone separator. In some cases, the product cannot even be collected as a dry powder.<\/p>\n\n\n\n

Une approche courante consiste \u00e0 ajouter des excipients tels que la dextrine ou l'amidon avant le s\u00e9chage afin d'augmenter le point de ramollissement du mat\u00e9riau. Cependant, lors d'un fonctionnement prolong\u00e9, l'adh\u00e9rence aux parois et les d\u00e9p\u00f4ts carbonis\u00e9s \u00e0 proximit\u00e9 du diffuseur d'air chaud, ainsi que les obstructions des conduits, peuvent tout de m\u00eame r\u00e9appara\u00eetre. Ces probl\u00e8mes nuisent \u00e0 la qualit\u00e9 du produit, n\u00e9cessitent des arr\u00eats fr\u00e9quents pour le nettoyage, r\u00e9duisent les rendements de production, entra\u00eenent un gaspillage d'\u00e9nergie et diminuent le taux d'utilisation des capacit\u00e9s.<\/p>\n\n\n\n

L'\u00e9volution du cadre r\u00e9glementaire a \u00e9galement renforc\u00e9 les exigences relatives aux op\u00e9rations de s\u00e9chage. La Chine a publi\u00e9 en 2025 les \u00ab Dispositions sp\u00e9ciales relatives \u00e0 la supervision et \u00e0 l'administration de la production de m\u00e9decine traditionnelle chinoise \u00bb, et le \u00ab R\u00e8glement d'application de la loi sur l'administration des m\u00e9dicaments \u00bb, r\u00e9cemment r\u00e9vis\u00e9, est entr\u00e9 en vigueur en 2026. En juillet 2026, la Chine avait publi\u00e9 11 s\u00e9ries de normes nationales relatives aux granul\u00e9s de formules de m\u00e9decine traditionnelle chinoise, couvrant plus de 400 vari\u00e9t\u00e9s. Les nouvelles r\u00e8gles imposent des exigences obligatoires en mati\u00e8re de traitement \u00e0 basse temp\u00e9rature, de param\u00e8tres de processus fixes et de tra\u00e7abilit\u00e9 de bout en bout, faisant de la modernisation des \u00e9quipements de s\u00e9chage une n\u00e9cessit\u00e9 urgente pour le secteur.<\/p>\n\n\n\n

Demande du march\u00e9 : les \u00e9quipements destin\u00e9s \u00e0 la R&D deviennent indispensables \u00e0 la modernisation de l'industrie<\/h2>\n\n\n\n

The TCM formula granule and Kampo granule industries have entered a period of strengthened regulation and standardization, and companies continue to increase R&D investment. During the development of new pharmaceutical and food products, formulation screening, process optimization, and small-scale trial production, pharmaceutical companies\u2014including TCM manufacturers\u2014and food companies have a clear need for small, precise, test-scale spray dryers capable of processing heat-sensitive extracts.<\/p>\n\n\n\n

As the small-scale model in this series, the ZLPG-5 bridges laboratory, pilot, and industrial scale-up, supporting customized requirements across the full chain from laboratory trials and pilot testing to commercial production. Before committing to large-scale manufacturing, users can use the system to validate drying processes, determine and fix key parameters, and evaluate batch consistency, reducing scale-up risks and trial-and-error costs.<\/p>\n\n\n\n

Principe de fonctionnement : atomisation rotative et s\u00e9chage \u00e0 courant parall\u00e8le pour une d\u00e9shydratation instantan\u00e9e<\/h2>\n\n\n\n

Le ZLPG-5 utilise une technologie d'atomisation rotative et de s\u00e9chage \u00e0 courant parall\u00e8le. L'air est filtr\u00e9 pour \u00e9liminer les impuret\u00e9s, puis chauff\u00e9 \u00e0 la temp\u00e9rature d\u00e9finie par un \u00e9l\u00e9ment chauffant, avant d'entrer dans le distributeur d'air situ\u00e9 en haut de la chambre de s\u00e9chage selon un flux spiral\u00e9 uniforme. Apr\u00e8s filtration, le liquide \u00e0 traiter est pomp\u00e9 vers l'atomiseur rotatif situ\u00e9 en haut, o\u00f9 la force centrifuge g\u00e9n\u00e9r\u00e9e par la rotation \u00e0 grande vitesse l'atomise en fines gouttelettes. Les gouttelettes entrent en contact avec l\u2019air chaud dans un flux \u00e0 courant parall\u00e8le, et l\u2019humidit\u00e9 s\u2019\u00e9vapore rapidement en 5 \u00e0 35 secondes, permettant d\u2019atteindre un taux d\u2019\u00e9limination de l\u2019humidit\u00e9 compris entre 90% et 98%. Le produit fini est \u00e9vacu\u00e9 par le bas de la tour de s\u00e9chage et du s\u00e9parateur \u00e0 cyclone, tandis que l\u2019air d\u2019\u00e9chappement est d\u00e9poussi\u00e9r\u00e9 et filtr\u00e9 avant d\u2019\u00eatre \u00e9vacu\u00e9.<\/p>\n\n\n\n

Gr\u00e2ce \u00e0 ses propri\u00e9t\u00e9s de s\u00e9chage instantan\u00e9, ce mat\u00e9riau ne reste que peu de temps dans la zone \u00e0 haute temp\u00e9rature. Cela permet de pr\u00e9server les principes actifs thermosensibles ainsi que la couleur, l'ar\u00f4me et la saveur du produit, r\u00e9pondant ainsi aux exigences des proc\u00e9d\u00e9s de s\u00e9chage doux requis pour les extraits de m\u00e9decine traditionnelle chinoise, les granul\u00e9s Kampo et les extraits de plantes.<\/p>\n\n\n\n

Performance Features: Anti-Wall-Adhesion, Moisture Protection, and Precise Temperature Control<\/h2>\n\n\n\n

Le ZLPG-5 a \u00e9t\u00e9 sp\u00e9cialement con\u00e7u pour s'adapter aux propri\u00e9t\u00e9s des extraits de m\u00e9decine traditionnelle chinoise. Ses principales caract\u00e9ristiques techniques sont les suivantes :<\/p>\n\n\n\n

(1) Air-jacket protection against wall adhesion. The drying-chamber walls and top are equipped with an air-jacket cooling system that reduces wall temperature and helps prevent material from softening, adhering to the walls, caramelizing, or degrading because of localized overheating.<\/p>\n\n\n\n

(2) Internal air-sweep system. The system includes a built-in air sweep that directs airflow along the internal walls to eliminate or reduce material adhesion. This addresses wall-adhesion issues while minimizing the use of excipients, helping maintain product purity and improve yield.<\/p>\n\n\n\n

(3) Dehumidified cooling and powder collection. A pneumatic dehumidified-air system regulates product temperature and maintains the dried powder in a low-humidity environment, helping prevent moisture absorption and caking while improving storage stability.<\/p>\n\n\n\n

(4) Precise temperature control. Inlet and outlet air temperatures are adjustable, with proportional control across a range of 100\u2013200\u00b0C and a control accuracy of \u00b11\u00b0C.<\/p>\n\n\n\n

(5) Compact design for R&D applications. The system has a small footprint and is suitable for laboratory and R&D environments. Drying-air cleanliness is better than Class 100,000, and the design is intended to meet GMP requirements. Parts in contact with the material and hot air are made from SUS304 or SUS316L stainless steel, making the system easy to clean and operate.<\/p>\n\n\n\n

(6) High level of automation. The system uses a PLC controller with an HMI touchscreen for inlet-air temperature display, pneumatic temperature display, automatic control, and alarms. Outlet-air temperature can be controlled manually or automatically and is equipped with alarms. The electric heater includes interlock protection, reducing the level of manual intervention required.<\/p>\n\n\n\n

Am\u00e9liorations techniques : optimisation structurelle syst\u00e9matique des propri\u00e9t\u00e9s d'extraction<\/h2>\n\n\n\n

Pour rem\u00e9dier au faible point de ramollissement et \u00e0 la forte hygroscopicit\u00e9 des extraits de m\u00e9decine traditionnelle chinoise (MTC), le ZLPG-5 int\u00e8gre des am\u00e9liorations structurelles cibl\u00e9es. Celles-ci constituent une conception int\u00e9gr\u00e9e visant \u00e0 pr\u00e9venir l\u2019adh\u00e9rence aux parois, la d\u00e9gradation et l\u2019absorption d\u2019humidit\u00e9, avec des am\u00e9liorations apport\u00e9es aux syst\u00e8mes d\u2019alimentation, d\u2019atomisation, de chambre de s\u00e9chage, de collecte de poudre et de contr\u00f4le. Ensemble, ces modifications font passer le fonctionnement de l'\u00e9quipement d'un processus reposant sur l'exp\u00e9rience \u00e0 une fabrication pr\u00e9cise et intelligente.<\/p>\n\n\n\n

Pour des raisons d'hygi\u00e8ne et de propret\u00e9, les composants du syst\u00e8me d'entra\u00eenement entrant en contact avec le produit sont efficacement \u00e9tanch\u00e9ifi\u00e9s. Une vanne papillon \u00e9tanche est utilis\u00e9e au point de d\u00e9charge, et la section de tuyau de d\u00e9charge \u00e0 tirage induit est \u00e9quip\u00e9e de raccords rapides facilitant le d\u00e9montage, le nettoyage, la d\u00e9sinfection et la st\u00e9rilisation. Ces caract\u00e9ristiques permettent d'\u00e9viter toute contamination crois\u00e9e lors des changements de produit et de respecter les exigences d'hygi\u00e8ne applicables \u00e0 la production pharmaceutique.<\/p>\n\n\n\n
